not all keys requested were satisfied

Working with Data

Hi,
We’re trying to use Mongo’s client side field level encryption, but sometimes we’re getting “not all keys requested were satisfied” exception.
What this error mean? What keys?

Thanks

It means that at least one key referenced in your collection schema by UUID cannot be found in your special encryption.__dataKeys collection.
Basically you asked Mongo to encrypt a field using a non-existent encryption key.
