Original Pull Request: https://github.com/langgenius/dify/pull/26627

State: open
Merged: No

Remove the reportUntypedFunctionDecorator hint from pyrightconfig.json and fix all resulting type errors.

This change enforces stricter type checking for function decorators by removing the setting that suppressed warnings for untyped decorators.

To resolve the newly surfaced errors, the following changes were made:

  • Added explicit type annotations (Callable, ParamSpec, TypeVar, overload) to all custom decorators in api/controllers/console/wraps.py, api/controllers/console/app/wraps.py, api/controllers/console/datasets/wraps.py, api/controllers/inner_api/plugin/wraps.py, and api/controllers/service_api/wraps.py.
  • Corrected the usage of decorators in api/controllers/service_api/dataset/dataset.py and api/controllers/service_api/workspace/models.py.
  • Added type hints to error handlers in api/libs/external_api.py.
  • Removed unused imports that were identified during the process.

All type-checking errors have been resolved, and the backend unit tests pass.
