Unable to create new items in collection

[MartinSRimsbo]

Hi!

Thanks for this! Retrieving and changing data in firestore from wix works great, but I am having trouble adding new items to firestore from wix.

I have so far only tested this by inserting a new item in the editor, and get a red exclamation mark saying:
Unknown error, request ID: 1585908515.2894064610008819168

Any ideas? Very grateful for any help.
Best
Martin
