Forwarders script is identified as missing in the MS-o365 logs but the script is there in $SPLUNK_HOME/splunk/etc/apps/Splunk_TA_microsoft-cloudservices/bin and also the permissions are accurate.
splunk_ta_ms_o365_rh_server_forwarders.py
This same error occurs for other scripts as well.
We started investigating when we saw a huge drop in events from the TA. We still see events but they are drastically cut.
