Problem Statement/Rationale

What is going wrong? What action would you like the Engineering team to take?

There is no validation to verify that numPartitions is an invalid parent level field for vector search indexes. The Atlas UI properly warns against this as an invalid parameter, but Compass allows you to create an index.

The index rebuilt fine, no warnings, no errors. But after the rebuild the "numPartitions" parameter was missing from the index definition. This might create a confusing customer experience

Please be sure to attach relevant logs with any sensitive data redacted.

The index is allowed to be built, with the numPartitions field not appearing anywhere within it
