Better reference to the violating field in an error of unique constraint

[faurehu]

The Prisma server is responding with the following error after updateEmployee call:

{
    "data":null,
    "errors": [{
        "message": "A unique constraint would be violated on Employee. Details: Field name = email",
        "locations": [],
        "path":["updateEmployee"],
        "code":3010,
        "requestId": "local:cjrb3kwep002f07437mcq7dje"
    }]
}

For my UI purposes, I would appreciate having a better reference to the field which is violating the constraint.

I also tried digging the code to have a better idea about where the error code comes from. I can only assume for now that 3010 means a unique field constraint is being violated.
