I want to use REST API Modular Input but I am getting this error:
6-01-2020 16:45:56.588 -0500 ERROR ExecProcessor - message from "/opt/splunk/bin/python2.7 /opt/splunk/etc/apps/rest_ta/bin/rest.py" FATAL Trial Activation key for App 'REST API Modular Input' failed. Please ensure that you copy/pasted the key correctly.
The key is correct. I try to use different keys but I have the same error.
