I am using CrewAI inside of an Open WebUI plugin. When I am trying to setup my Python code that uses Crew AI inside of an open webui function, I get this super bizarre opentelemetry error. This only happens when I run it in a docker container -- not when I am running Open WebUI outside of a docker container, despite having identical Python package versions of just about everything, including Opentelemetry. Any thoughts here?
The error: cannot import name 'SpanFlags' from 'opentelemetry.proto.trace.v1.trace_pb2
