PR-Agent on gitea will not run

[mars3142]

services:
    pr-agent:
      image: codiumai/pr-agent:0.32-gitea_app
      entrypoint: ["python", "-m", "pr_agent.servers.gitea_app"]
      environment:
        - CONFIG__GIT_PROVIDER=gitea
        - CONFIG__IS_SERVER=true
        - GITEA__PERSONAL_ACCESS_TOKEN=<secret>
        - GITEA__URL=https://<custom_domain>
        - CONFIG__MODEL=gemini/gemini-2.0-flash
        - CONFIG__FALLBACK_MODELS=["gemini/gemini-2.5-flash"]
        - GOOGLE_AI_STUDIO__GEMINI_API_KEY=<super_secret>

This is my setting in Portainer for the PR-Agent and every time I use the webhook, I got:

  File "/app/pr_agent/git_providers/__init__.py", line 67, in get_git_provider_with_context 
     raise ValueError(f"Failed to get git provider for {pr_url}") from e
ValueError: Failed to get git provider for https://<custom-domain>/<owner>/<project>/pulls/<id>
