**Summary**
When submitting a POST to /users/{user_id}/collected_items, a 400 with the message "Invalid collection <collection_id>" even when the int specified in the error message is valid.
**Details**
I detailed the Python calls and process, as well as included a verbose debugging output in a gist here:
https://gist.github.com/namachieli/7bb0271f415d796744ba47506c76146f
You can see where i fetch the list of collections with IDs to verify the ID is valid for the user.
I also Verified this behavior was consistent by using the API Client in the API Documentation GUI using the same data used as the input to the Python SDK. (Attached Pictures)
