"error": "rule not matched for function \"data/v1/endpoint in mongoDB Data api

I have reviewed the MongoDB Realm documentation and verified my implementation, but I'm unable to identify the root cause of this issue. The error seems to suggest that a rule is not being matched for the insertOne function.

Could someone provide insights into what might be causing this error and how I can troubleshoot it further? Additionally, if anyone has encountered similar issues or has experience with MongoDB Data API, any advice or guidance would be greatly appreciated.
