That is the problem. The Synology Docker can not connect to GitHub. I am looking for how to install it.
Seeing the same, except a different line number:
[ERROR - PLEX] Exception in EPG Scheduler : not well-formed (invalid token): line 23939, column 746
Don't you still have several days worth from the earlier calls? I've got guide data through the 31st:

The good news is that we do already have the list of tmsid's!
Install Portainer and OliveTin-for-Channels, and you'll have every Channels-related project a click away using Project One-Click:
Yeah...I use SLM for that reason. Some things need manual mapping to gracenote
I'm a huge fan of Stream link manager myself. Thinking of going in and just mapping the channels i care about.
I want to get rid of some of this need for xmltv.
If you're using Synology Container Manager, read the built in help for
Container Manager > Registry (That would be the question mark at the upper right)
You can Add registries in Container Manager > Registry > Settings
I prefer to use Portainer.
Get familiar with the tool you're going to use to manage your docker containers.
That is what I tried to do. It gets an error searching GitHub.
I have those daily files, but Channels DVR pulls from the merged epg.xml, which isn't getting updated in my case.
I just now deleted the container and image and redeployed it. Will see if it works.
Nope. Still errors out.

I'll try stopping the container, deleting all the *.xml files and restarting it.
That didn't work. It's still not creating/updating the merged epg.xml
I stopped the container, deleted every file in /app/data and restarted the container.

Did you add https://ghcr.io


I used https://github.com and also added my username and pswd to both entries. This is what I get with https://github.com
Model: DS412+
DSN Ver. DSM 6.2.4-25556 Update 8
That is the current version
Not for $149 
The CE version (Community Edition) is fully functional. And free.
Ahh, I'm running
DSM 7.2.2-72806 Update 4
Container Manager 24.0.2-1543
Your 13 year old NAS is too old to run DSM v7.
I had Perplexity give me step by step directions on how to pull plex-for-channels from GitHub using TELNET. It worked. Now to get it operational. 
I thought about getting a new one, but this one does everything I need. 
Is anyone else getting this error in their container log (besides babsonnexus), or are we the only ones?
I do a blend of container manager and command line via SSH.
I was at one point thinking about getting a DS224 plus and building up a system with solid state drives. I was even thinking about getting onfe of those mini pcs and running Linux on the system.
My Synology so far is doing what i need.
