Whenever I run metagpt --project-path <my_existing_project_path> "some new feature/incremental code" , I get the following error:

Is the existing project code you want to improve created by MetaGPT?

[krish240574]

Yes, I started the project using metagpt "project specs". Then continued using metagpt --project-path "incremental feature" Thanks, Kumar

Could you please upload the generated project code? I can try to reproduce this issue.

[krish240574]

I'm afraid I can't, since the code is now company-internal. I simply followed the steps in the documentation, metagpt "new project specs" - it generated some code ok. Then I did metagpt --project path <project_path> "description of new feature to be added".
