### Dependencies with `yield` and `except`, Technical Details { #dependencies-with-yield-and-except-technical-details }

Before FastAPI 0.110.0, if you used a dependency with `yield`, and then you captured an exception with `except` in that dependency, and you didn't raise the exception again, the exception would be automatically raised/forwarded to any exception handlers or the internal server error handler.
