Describe the bug:
I'm using elastic APM with Django 3.1.2 and graphql.
On every GraphQL Query, I'm seeing now this error: AttributeError: 'FragmentDefinition' object has no attribute 'operation'

The relevant file is: elasticapm/instrumentation/packages/graphql.py in get_graphql_tx_name at line 99

To Reproduce
I'm not sure yet, why the error is occurring and I'm just getting started with the service. If you can guide me to the right direction, I can create a reproducible example.

Environment (please complete the following information)

• OS: Linux docker Container

• Framework and version : Django 3.1.2
