"Failed to parse validation script output" for remote Docker compose CLI interpreter

Could not open input file: /opt/.phpstorm_helpers/phpinfo.php

That typically means there's something in your docker-compose config that prevents the container that IDE creates to communicate with your app. Is it possible to share your docker-compose & all related config files? 

You can share them privately at https://uploads.jetbrains.com/, just let us know the upload ID.

Hello! 

Have you an solution about this error?
I am exatally the same error :/ 

Same problem here after updating to 2022.2.3

There's still no solution to this because the details of the issue are unclear. It would be great if you could send us more info about your setup/project via Help | Contact Support or describe it here.

Would it help if you re-add this PHP Interpreter?

Would it help if you change the lifecycle of the interpreter to "docker-compose run" instead of "docker-compose exec"?

Dmitry Tronin hi!

Both options, run and exec, are have the same error. See into my print screens.


This is my docker-compose.yml:

version: '3.9'
services:
  api_cadastrodasorte:
    build:
      context: .
    volumes:
      - '..:/var/www/html/cadastrodasorteapi.belezanatural.com.br'
      - './cadastrodasorteapi.belezanatural.com.br.conf:/etc/nginx/sites-enabled/cadastrodasorteapi.belezanatural.com.br.conf'
    ports:
      - '8081:80'
    entrypoint:
      - /opt/99-entrypoint.sh
    working_dir: /var/www/html/cadastrodasorteapi.belezanatural.com.br
    environment:
      PHP_IDE_CONFIG: serverName=cadastrodasorteapi.belezanatural.com.br

Docker configuration on PHP Storm > Settings:

I am using the Rancher Desktop on version 1.6.2 with dockerd as container engine.

My PHP Storm version/build:


The generated log is the same sent by Mr Wolowski.

Do you need some information more?

Thanks. I can see your docker-compose.yml file is in a subfolder. 

Would it work if you move it inside the root of your project? Volume mappings inside the file itself would have to be adjusted in that case.

2022.3 Beta fixed the issue for me

Dmitry Tronin
I try it, but doesnt work too :/
So, I installed 2022.3 Beta like Matt was mensioned, but doesnt work again.

Can you share your entrypoint and Dockerfile files? 

Does running docker compose run api_cadastrodasorte php -v manually in terminal work?

I managed to fix it, but the unfortunate thing is that I don't really know how.

Yesterday I did some testing because it worked for some of my projects and for some it didn't. My projects tend to have similar docker-compose configurations, but I established that it was a docker-compose.yml value

PHP_IDE_CONFIG=serverName=docker_dev_${PROJECT_NAME}

that somehow made the difference. It's the only place where the PROJECT_NAME variable was used so basically it was down to PHP_IDE_CONFIG. But I don't know why it would work for some values and for others not.

Today I opened the project in question and found that it now works (regardless of the PHP_IDE_CONFIG value).

The other thing that could be a factor is that I'm managing my PhpStorm settings using a GitHub repository and a couple of days ago my PAT token that is used in communication with GitHub expired. Earlier today I generated a new one and synced IDE settings using Overwrite Remote option. I'm not sure how this could be related, but just for the record.

Thanks! Looks similar to https://youtrack.jetbrains.com/issue/WI-59878. If that happens again - feel free to submit that as a new bug report at https://youtrack.jetbrains.com/newIssue attaching some files that reproduce the issue - we'll investigate that closely.

Exact output than Diego at https://intellij-support.jetbrains.com/hc/en-us/community/posts/8402591953554/comments/8519244465426 a few comments before.

I'm using two separated projects with `docker-compose` in `network_mode` set to `bridge`. Having two windows with PHPStorm on each project, one connect without any problem while the other shows same output on log file, as well as in the UI.

The version of PHPStorm I'm using is:

PhpStorm 2022.3
Build #PS-223.7571.212, built on December 1, 2022

Runtime version: 17.0.5+1-b653.14 amd64
VM: OpenJDK 64-Bit Server VM by JetBrains s.r.o.
Linux 5.15.0-56-generic
GC: G1 Young Generation, G1 Old Generation
Memory: 1960M
Cores: 8
Registry:
    run.processes.with.pty=TRUE

Current Desktop: KDE

`docker-compose` version is `v2.14.0` and `docker` daemon and cli is `20.10.21 build baeda1f`.

My `docker-compose.yml` are extremely simple, using `version: '3.4'`. For the record, an example:

version: '3.4'

name: 'backend'

services:
  php:
    network_mode: bridge
    build:
      context: ../
      dockerfile: .docker/Dockerfile
    environment:
      PHP_IDE_CONFIG: "serverName=localhost"
    volumes:
      - ../app:/srv/app
      - ./php:/usr/local/etc/php
      - ~/.ssh/:/home/root/.ssh

  web:
    network_mode: bridge
    links:
      - 'php:php'
    image: nginx:1.19-alpine
    working_dir: /srv/app
    volumes:
      - ../app:/srv/app
      - ./nginx:/etc/nginx/conf.d
    ports:
      - "8080:80"
    depends_on:
      - php

Any idea here?

I made it work. Based in some other tickets in YouTrack, a env variable was missing under the desired CLI. So, in my case, the `COMPOSE_PROJECT_NAME` should be set as the same value than the key `name` in your `docker-compose.yml` file.

I was dealing with the same error. I managed to fix that by changing a configuration on: Settings > Build, Execution, Deployment > Docker > Tools and checking the box "Use Compose V2"

After that, I went to the PHP CLI configuration and just pushed the refresh button, and it works

+1

I am facing the same issue 

I'm using Docker composer with a PHP. When trying to set the interpreter I choose Docker compose and connecting with existing container and then it fails with the error "Failed to parse script validation output".

If I execute php -v inside the container everything seems fine,

What is the expected result?
An installed php version should be shown

What happens instead?
Failed to parse validation script output message and PHP version: not installed label

It's working fine with docker-compose run lifecycle

PS:

OS : RHEL 8.8

ddev version v1.21.6

Unfortunately, `Failed to parse validation script output` and `Content is not allowed in prolog` are pretty generic messages and there is a whole bunch of reasons why they may appear.

Usually, more detailed logs could help to understand the situation deeper. To increase the log level, you might want to add the following lines to "Help > Diagnostic tools > Debug logs settings":
#com.jetbrains.php
#com.intellij.execution

@Minalsharma888 Would it be possible to enabled the extended logging, reproduce the issue, collect logs (Help > Collect Logs...) and submit a YouTrack issue?

Below new issue has been submitted : 
https://youtrack.jetbrains.com/issue/WI-73058/PhpStorm-and-Docker-Unable-to-configure-the-Remote-PHP-interpreter-Failed-to-parse-script-validation-output

I had the same issue.
Solved it by lowercasing the environment variable for the project name.

Docker setup base on DDEV
With phpstorm DDEV plugin

phpstorm: 2023.2.4
phpstorm: Build #PS-232.10227.13
ddev version v1.22.5

The suggestion for the environment variable put me in the right direction.
Issue in my case was the case sensitivity.

My project name has a capital in it: ddev-D10-study
That name was set correctly as environment variable in phpstorm: COMPOSE_PROJECT_NAME=ddev-D10-study
But in the .yaml configuration file for the DDEV docker setup it appeared to be lowercase: name: ddev-d10-study

So in phpstorm I changed it to lowercase: COMPOSE_PROJECT_NAME=ddev-d10-study
And that did the trick.

I had this problem on Windows. In the PhpStorm configurations, Docker was usingWSL, but inside the PHP Interpreter, I configured it to use Docker for Windows. I did Build, Execution and Deployment > Docker and selected Docker for Windows instead of WSL. It fixed the problem

Not sure if it's relevant but I had issues adding a docker compose interpreter, not even getting through the initial dialogue window where it would infinitely ‘checking php configuration’. 

My docker-compose.yml came from laravel sail which includes these environment variables:

environment:
	XDEBUG_MODE: '${SAIL_XDEBUG_MODE:-off}'
	XDEBUG_CONFIG: '${SAIL_XDEBUG_CONFIG:-client_host=host.docker.internal}'

When I removed these it would work. Even if I just set debug and host.docker.internal without the ${} it wouldn't work. I set the config in a php.ini (CLI) and xdebug.ini (web) that gets copied to the relevant paths within the container in the dockerfile so it's not a big deal to remove them from docker-compose.yml. 

I'm using phpstorm v2024.2.3 non EAP and I don't use DDEV.
