AdminManagerExternal error

[Steve_S]

Really intrigued by the notion of this app; installs great but have been getting a "Could not connect to REST API. Status 500" error in the app when uploading an ARF .xml file generated by CIS-CAT Assessor Pro v4.59.0.

Have replicated on Splunk Enterprise 9.4.9 and 10.0.2 running on Debian 13 with no SSL certificate; CIS-CAT Assessor running on Windows, and xml files uploded via Edge or Firefox. Nothing in the Splunk python.log file, text from splunkd.log as follows:
