"package.json not found" error in cloudbuild

Hello! I added ML-Agents to my project and when I try to CloudBuild it, I get an error.

How to add ML-Agents to Project I installed ML-Agents Extensions package (com.unity.ml-agents.extensions) locally according to the following URL. https://github.com/Unity-Technologies/ml-agents/blob/main/com.unity.ml-agents.extensions/Documentation~/com.unity.ml-agents.extensions.md I put it in folder D:/ml-agents/.
Training works fine.

Error excerpts > 560: [Unity] An error occurred while resolving packages:>>561: [Unity] Project has invalid dependencies:>562: [Unity] com.unity.ml-agents.extensions: The file [/BUILD_PATH/mygame.mygame_unitycloudbuild/Packages/D:/ml-agents/com.unity.ml-agents.extensions/package.json] cannot be found>563: [Unity] A re-import of the project may be required to fix the issue or a manual modification of /BUILD_PATH/mygame.mygame_unitycloudbuild/Packages/manifest.json file.>564: Unity ran in '65.563104' seconds>565: ! Unity player export failed!

I have confirmed that the following line has been added to Packages-manifest.json on Git. "com.unity.ml-agents.extensions": "file:D:/ml-agents/com.unity.ml-agents.extensions", Do I need to rewrite the manifest file? If so, how do I rewrite it so I can build?
Thanks for reading.
