When testing db.runCommand( {"listSearchIndexes": <collection>, "name":<indexName>}) using mongosh, we got flaky result with error BSONError: bad embedded document length in bson

We used mongosh version 2.0.2, mongodb version 6.0.13 with 2 shards and 3 mongod nodes both with and without dedicated search nodes.

Our e2e test also suggests flaky results on version 6.0 and here is the error log  for e2e tests.

Note: We don't see this error on un-sharded clusters
