Hi,

I have the below regex and Splunk keeps telling me I have a mismatched "[" and for the life of me I can't figure out where

rex field=properties "\"url\":\"[^"]+\/(?<final_segment>[^"?]*)(\?[^\/"]+)?\""

@dbcase, you would need to escape double quotes in the regular expression for SPL.
Try the following run anywhere search:

| makeresults
| eval properties="\"url\":\"https://www.google.com\""
| rex field=properties "\"url\":\"[^\"]+\/(?<final_segment>[^\"?]*)(\?[^\/\"]+)?\""
____________________________________________
| makeresults | eval message= "Happy Splunking!!!"
