Error adding series to Sonarr

[Schnoopie-Doopie]

When the script runs it adds movies to Radarr using the tag defined with no issues however displays an error when adding to Sonarr with or without a tag.
The error is

"Unknown Error: 'Series' object has no attribute 'extend'"

Even with the Sonarr logging turned to debug, the report shows the below

I do have Sonarr and Radarr configured with a base URL for reverse proxy needs and both have a login using the forms style. I cannot see any base config differences between Sonarr and Radarr except for the root folder path. In Radarr it doesnt have a space however with Sonarr it does. I contain this in quotes "" as demonstrated in the template example however on running the script these are removed. My config extract is below:

Any help would be great.
