I get this error both from GUI and from API usage. No document is able to be created. I have no index for this collection. No relationship. Cloud.
As you can see the ID being used is a random new one generated by Appwrite.
TL;DR
Developers are unable to create new documents, receiving an error despite the ID being generated by Appwrite. No documents exist even though the ID does. This occurs in both GUI and API usage, with no associated index or relationship in the collection.
