I'm recently having problems with a python flask application running on
uWSGI v2.0.12. This service is a REST API. What brought my attention to
uWSGI is when the API periodically would return 500 Internal Server error
responses for calls that should always return 200 success. Even requests
that happen on a frequent basis fail some of the time but not all of the
time. It does not seem to have anything to do with the request itself (i.e.
the data in the request is correct).

Digging through the logs I noticed that each time a 500 response would
happen, a log would be written with the text "no python application found".
I then started looking for where this string would be coming from, and
found it in the uWSGI native code.

At this point I am trying to understand what could be the origin of this
error. I notice that the string would only ever get logged when the
application id is found to be -1. What is not clear to me right now though
is what would cause that to happen?

I can provide whatever information you need that I have not included in
this message in a reply.
