Bug Report for acp-sdk. /docs #111
Description
Description:
The /docs endpoint fails to generate OpenAPI schema due to a Pydantic compatibility issue with the ResourceLoader class in acp_sdk.shared.resources.
Environment:
OS: macOS 24.6.0
Python: 3.11
acp-sdk: 1.0.3
uvicorn: 0.30.0
pydantic: 2.2.0
fastapi: 0.119.0 (installed as dependency of acp-sdk)
Error:
Minimal Reproducible Example:
Steps to Reproduce:
Install acp-sdk==1.0.3
Run the above code
Navigate to http://127.0.0.1:8000/docs
The page loads but shows "Failed to load API definition" error
Check server logs for the PydanticSchemaGenerationError
Expected Behavior:
The /docs endpoint should load the OpenAPI schema successfully and display interactive API documentation.
Actual Behavior:
The /docs page loads but fails to generate the OpenAPI schema, showing "Failed to load API definition" error.
Additional Notes:
The server runs successfully and agent endpoints work via direct HTTP requests
The issue only affects the OpenAPI documentation generation
The error suggests setting arbitrary_types_allowed=True in model_config or implementing get_pydantic_core_schema method
This appears to be a compatibility issue between acp-sdk and newer versions of Pydantic
Workaround:
None found. The core functionality works, but documentation is broken.
