verifyPlugin error

Hi, I switched to the 'org.jetbrains.intellij.platform' version ‘2.0.1’, and my plugin builds and runs OK on Pycharm 2024.2

When I start the gradle task verifyPlugin, I get this error message:

* What went wrong:
Execution failed for task ':verifyPlugin'.
> The following files specified for the verification are not valid plugins:
     C:\Users\Macko\source\repos\RsIC\build\distributions\RsConnectivityPycharmPlugin-3.4.0.zip
         Plugin problems:
             Invalid plugin descriptor 'plugin.xml'. The property <code> is not specified.

I checked the help for the ‘plugin.xml’ and the <code> is only used for paid plugin, which mine is not.

The question is: How do I tell the verifier that my plugin is not a paid plugin?

Thanks

Milo
