topic Re: Error when importing custom python modules in splunk V9.x.x+ in Splunk Enterprise

Why is there an Error when importing custom python modules in splunk V9.x.x+?

Hi,

while importing custom modules (e.g. `from logger import Logger`) in the splunkd.log we are able to see `ModuleNotFoundError: No module named 'logger'` error and this is generated by this file "/opt/splunk/lib/python3.7/site-packages/splunk/persistconn/appserver.py" .We suspect somehow library is not able to identify internal modules and hence throwing error.

We are also able to see warning `DeprecationWarning: the imp module is deprecated in favour of importlib; see the module's documentation for alternative uses` in same log file.

This issue seems to be on splunk version 9.0.x. For splunk version 8.2.x it is working fine. As we have noticed main difference in these 2 versions is python 2.7 support is removed from version 9.0.x.

We will like to know the possible solution in solving this error.

@jabezds - Are you getting the full exception trace? Is the error originating from any Python file you have or from a third-party App?

@VatsalJagani yes we are getting a full trace back, Its from our 3rd party app.
