Corrupted registry breaks usage of feature store #3703
Description
Expected Behavior
Connecting to the feast registry and pulling features from a connected registry should work without an issue.
All feature views should be callable.
Current Behavior
The registry entry for one of four feature views seems to be corrupted. Opening a new connection succeeds for the first three features. Upon calling the fourth feature, the instantiation fails with the following error. This errors occurs regardless of the location from which we run store = FeatureStore(config=repo_config).

Steps to reproduce
We haven't been able to reproduce the error yet. We have a CI job running feast materialize-incremental every 5 mins, pushing the same demo data. That job started failing at some point without any changes in the data, dependencies or setup in general.
Authentication and manual querying of the registry and databases works fine.
Specifications
- Version: feast == 0.31.1, python == 3.10.10
- Platform: AWS, registry: RDS, online store: dynamodb, offline store: redshift
- Subsystem:
Possible Solution
We dumped the feature store and recreated it running feast apply. This is fine for now since we are in an experimental setup. Once we move towards using feast in production, we would like to have an understanding of what is happening here and how to resolve this without dumping the whole feature store.
