Custom Channel EPG error

I have added a custom m3u url edited with a m3u/epg editor (Iptv boss) the trimmed down channels show up with no issue but the exported xml (epg) is blank with this error in the logs. [ERR] Failed to get placeholder channels for lineup XMLTV-streamprovider: XML syntax error on line 1: element

closed by . Just to test I added same m3u and xml to a Jellyfin test setup and everything works fine.

Email the xml file to [email protected]

I just started having this same issue, did you ever find a resolution? I have the exact same setup, generating XML files with IPTVBoss.
