RecursionError: maximum recursion depth exceeded while calling a Python object

[thisjustin]

Following up, this was happening before we added celery to the project so the root is something else. We're on python 3.6.3 if that helps.

[J3VS]

This is affecting me too. Every time I edit a file used by hug, I get this exception and have to restart. I'm also using celery, but this issue predated me integrating it.

[bbenne10]

I'm seeing this with absolutely no usage of celery. The constant restart cycle is maddening...

[ktomala]

Can confirm that this issue occurs with the latest develop.

[nilsdebruin]

I have the same issue. As a workaround I have created the following bash script:

run_local.sh

COMMAND='hug -f api.py'
LOGFILE=restart.txt

writelog() {
  now=`date`
  echo "$now $*" >> $LOGFILE
}

writelog "Starting"
while true ; do
  $COMMAND
  writelog "Exited with status $?"
  writelog "Restarting"
  WAIT 1
done

[fordguo]

I have the same issue with python 3.6.5 and the develop branch.

[lovato]

Same here. Thanks @nilsdebruin for the script idea. I just had to use "sleep 1" instead of "WAIT 1", since I have no such command in bash. I also added #!/bin/bash on the top.

[medariox]

Same here with the newest release (2.4.1). I'm pretty sure it has something to do with running hug in a virtual environment (I'm using Pipenv).

[mandeepm91]

I was facing this issue with Python 3.6.9. Then I installed Python3.7, deleted the old virtual environment, re-created one using Python3.7 and did a pip install. Everything worked fine
