Description of issue:
I’m trying to import some episodes and am running into this issue. I think the issue is specifically with the two shows, The Haunting and The Haunting Of.

Definitely possible, could you post the full debug somewhere and link it here?

It is manifesting itself when trying to generate the metadata for Young Sheldon
As you can see from the logs I’m on version 3.0.6.1196 on a docker image running on raspbian.

Could someone help me with this?

Thanks
