steinwaywhw opened a new issue, #53091: URL: https://github.com/apache/airflow/issues/53091
### Apache Airflow version
3.0.2
### If "Other Airflow 2 version" selected, which one?
_No response_
### What happened?
I'm trying to view connections by navigating to the Connections page on the
Airflow 3 UI, and I saw the following errors from the API server. It is a
Pydantic error trying to validate the ConnectionCollectionResponse object.
However I can't figure out where the "Invalid Token" attribute comes from.
For reference here's the backend config.
```
backend =
airflow.providers.amazon.aws.secrets.secrets_manager.SecretsManagerBackend
backend_kwargs = {"connections_prefix": "<redacted>", "variables_prefix":
"<redacted>", "config_prefix": "<redacted>"}
```
```

### What you think should happen instead?
_No response_
### How to reproduce
In our environment all you need to do to reproduce is to visit the
Connections page. However I suspect this is related to the secret backends
and/or the connections we have. So it is hard to know how to reproduce outside
of this environment.
