I’m currently working on setting up client-side field level encryption (CSFLE) using Node.js, Express, and Mongoose, following the tutorial for Use Automatic Client-Side Field Level Encryption with AWS. I’ve ensured that all the steps recommended in the tutorial have been followed, and I’m running a MongoDB Enterprise server.

However, when I try to insert a document using the secure client, I encounter the following error:
Error: MongoServerError: BSON field 'FindCommandRequest.jsonSchema' is an unknown field. This command may be meant for a mongocryptd process.

Has anyone encountered this issue before, or does anyone have insights on how to resolve this error?

Any help or guidance would be greatly appreciated!

Thank you!
