--- BEGIN ISSUE ---
'FragmentDefinition' object has no attribute 'operation'"
**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
- Python version:
- Framework and version : Django 3.1.2
- APM Server version: 
- Agent version: 5.9.0


**Additional context**
