The error means your props.conf or transforms.conf has an error in it. Can you post the offending stanzas here? If you're not sure where the config files are try
$SPLUNK_HOME/bin/splunk cmd btool props list --debug | grep REPORT-ua
That should tell you which file contains the offending config item
I extracted a new valus using separated values extraction and I had the same problem :
Failed to properly initialize the key-value parser for transform_name 'REPORT-.....'. You must define least one delimiter.
Command $SPLUNK_HOME/bin/splunk cmd btool props list --debug | grep REPORT-....
doesn't return any result. Any idea?
Solution good for me : changed [REPORT-SYSTEM] DELIMS = "\"" instead of [REPORT-SYSTEM] DELIMS = """ IN
same result con be achieved typeing \" directly in console during field extraction insteaad of ".
