Python errors when upgrading Splunk_TA_New_Relic to 2.2.0

[spavin]

Hi all,

I have recently upgraded the Splunk_TA_New_Relic to v 2.2.0 on Splunk 8.0.7.

Version 2.1.0 worked fine, but after the upgrade to 2.2.0 I started getting a lot of python errors.

Has anyone found this before or know a solution?

I'm going to try to set the python version to use 2.7, but wondering if there is something else we need to do to get the new version up and running.

Here's a sample of the python error:
