Hi Team,
We have received sometimes the below docker logs error from the worker when the query is trying to run. Am I think it correctly, that we received this errror when the connection pool is full? Or What is caused this type of error?
Traceback (most recent call last):

data, error = query_runner.run_query(annotated_query, self.user)
