Error when trying to update the watchlist for a group via API (PUT groups/{id}.json)

Thanks a ton, @zogstrip ! Works now ! :smiley:

(and just for reference, the "update_existing_users”=True has to be outside/parallel to the “group” item in the json sent over (shown here in Python syntax, so True gets translated to the string “true”):

            jsonData={
                "group": {
                    "name": f"{groupName}",
                    "watching_category_ids": newWatchList,
                },
                "update_existing_users": True,
            },
