RelationComponentConfigChangeSet has no method named

Error message

RelationComponentConfigChangeSet has no method named '{name}'

What it means

Catch-all arm of the Jinja method dispatch on RelationComponentConfigChangeSet: only 'get' is implemented, so any other method name invoked on _configuration_changes.changes raises this UnknownMethod error.

Solutions

1. Use the supported 'get' method
2. Fix the typo in the template's method name
3. Extend the match arm if a new accessor is genuinely needed
