Invalid key in stanza [proofpoint_digital_risk_audit_input://Digital_Risk_Data_Input] in /opt/splunk/etc/apps/TA-proofpoint-digital-risk-app-for-splunk/local/inputs.conf, line 2: token (value: xyznkbejrfhrekfjrltjgltrkgltrkgtkhgythytlhmylth).
Normally that means that you've put some key that shouldn't be there in a config stanza. Infortunately, this is a third-party provided app for which the authors didn't give any docs or even contact info. So it might be a bad config but also can be a bad spec file (the file defining proper syntax and elements for app's config).
If this is for an input that the GUI dialog created for you, it's probably the latter.
BTW, it's polite to actually ask the question if you expect an answer.
