How do I turn off the "label is not a valid value for slot. Expected: " warning Follow

can't reproduce with similar code. What IDE version is it, do you have a sample project you can share that reproduces the issue?

I didn’t have this warning when I was in a single file, but I got this warning when I created a component in a vue project. My IDE version is 2022.03. I uploaded a new vue project, using vue2+element , below is my code, on my current computer there is this warning.

<template>
  <el-descriptions class="margin-top" title="带边框列表" :column="3" :size="size" border>
    <template slot="extra">
      <el-button type="primary" size="small">操作</el-button>
    </template>
    <el-descriptions-item>
      <template slot="label">
        <i class="el-icon-user"></i>
        用户名
      </template>
      kooriookami
    </el-descriptions-item>
    <el-descriptions-item>
      <template slot="label">
        <i class="el-icon-mobile-phone"></i>
        手机号
      </template>

    </el-descriptions-item>
    <el-descriptions-item>
      <template slot="label">

      <template slot="label">

thanks, reproduced with your demo. As far as I can see, the IDE can't resolve element-ui components, thus the issue. Seems to be a problem with this particular library version. To improve code completion for different Vue.js component libraries, we have invented a special format of metadata, called web-types, as it's not always possible to resolve components defined in third-party libraries using static code analysis. web-types describe the library's components and their directives and slots.

element-ui@2.15.12 does have "web-types": "./web-types.json" in its package.json, but the file itself is missing in library distribution (https://github.com/ElemeFE/element/issues/22261). So all components and slots are unknown

Thank you very much for your help, now my problem has been solved, I will continue to support your products

I met this issue either, plz tell me how to turn off the warning. Not just using web-types.

Such issues are specific to libraries/components being used, there are no generic solutions. Please file a new ticket to youtrack, https://youtrack.jetbrains.com/issues/WEB, providing a code sample the issue can be repeated with
