GQL ariadne hook throws blocking error

[jollysahil]

Description
Ariadne GQL execute wrapper throws an unhandled error. The same GQL operation succeeds when newrelic is disabled.

Expected Behavior

1. There shouldn't be an error thrown
2. Errors in wrappers should be handled and not block critical operations

Troubleshooting or NR Diag results

Steps to Reproduce
Not all GQL operations are failing due to this, I cannot share our specific operations
