Oct 1, 2024October 2024 highlights: Stabilized Chargebee Vertex removal path in atlas-metastore by adding defensive checks and error handling. Implemented non-empty typeName validation before type registry lookups and attribute processing, preventing NullPointerExceptions during Struct vertex removal and ensuring graceful failure when typeName is not found. This improves reliability, data integrity, and reduces operator toil in Chargebee-related workflows. Commit MM-3720: 2e37d392bee9029dc6c87c5c197f9794ef3e5801.
