RuntimeError: Failed to stop profiling. Make sure that you start/stop profiling on the same thread.
I am not quite sure what to do about the error
RuntimeError: Failed to stop profiling. Make sure that you start/stop profiling on the same thread.
It happens regularly, but not for every request. It also affects different endpoints. The endpoints use SQLAlchemy with the following config:
db_engine = create_engine(
f"mysql+mysqlconnector://{config.DB_USER}:{config.DB_PASSWORD}@{config.DB_HOST}:{config.DB_PORT}/{config.DB_NAME}",
connect_args={"connect_timeout": 10},
pool_recycle=3600,
pool_pre_ping=True,
pool_size=10,
max_overflow=40
)
For example:
@router.get("/get_list", status_code=200, response_model=list[SchemaOut],)
def get_list(
session: Session = Depends(create_session),
):
data = session.query(
[..]
).join(
[..]
).filter(
[..]
).order_by(
[..]
).all()
return data
There is only one uvicorn worker that is started with
pipenv run uvicorn app.api:app
Is it possible to disable profiling? It seems optional in the web ui. I would also be thankful for help finding the source of the error. I do not really know how to debug this.
