In SERVER-59666, we prohibited system.buckets collection from being renamed by the user, but the applyOps code path can run into this check that was added.
There is a build failure where the TenantMigrationWriter renames a system.buckets collection to a temporary name:
[j4:rs1:prim] | 2021-10-05T02:42:08.680+00:00 I COMMAND 20309 [TenantMigrationWriter-0] "CMD: create -- renaming existing collection with conflicting UUID to temporary collection","attr":{"newCollection":"tenantMigrationTenantId_clustered_index_options.system.buckets.clustered_index_options","conflictingUUID":{"uuid":{"$uuid":"ee6edfb2-ca25-4b88-8334-c2fe7afc9eaa"}},"tempName":"tenantMigrationTenantId_clustered_index_options.tmpuBcvQ.create"} [j4:rs1:prim] | 2021-10-05T02:42:08.680+00:00 I STORAGE 20319 [TenantMigrationWriter-0] "renameCollection","attr":{"uuid":{"uuid":{"$uuid":"f01ae87b-2bc7-4d5a-94c6-8e62c623d99b"}},"fromName":"tenantMigrationTenantId_clustered_index_options.system.buckets.clustered_index_options","toName":"tenantMigrationTenantId_clustered_index_options.tmpuBcvQ.create"} [j4:rs1:prim] | 2021-10-05T02:42:08.682+00:00 I STORAGE 20320 [TenantMigrationWriter-0] "createCollection","attr":{"namespace":"tenantMigrationTenantId_clustered_index_options.system.buckets.clustered_index_options","uuidDisposition":"provided","uuid":{"uuid":{"$uuid":"ee6edfb2-ca25-4b88-8334-c2fe7afc9eaa"}},"options":{"uuid":{"$uuid":"ee6edfb2-ca25-4b88-8334-c2fe7afc9eaa"},"validator":{"$jsonSchema":{"bsonType":"object","required":["_id","control","data"],"properties":{"_id":{"bsonType":"objectId"},"control":{"bsonType":"object","required":["version","min","max"],"properties":{"version":{"bsonType":"number"},"min":{"bsonType":"object","required":["time"],"properties":{"time":{"bsonType":"date"}}},"max":{"bsonType":"object","required":["time"],"properties":{"time":{"bsonType":"date"}}},"closed":{"bsonType":"bool"}}},"data":{"bsonType":"object"},"meta":{}},"additionalProperties":false}},"clusteredIndex":true,"expireAfterSeconds":10,"timeseries":{"timeField":"time","granularity":"seconds","bucketMaxSpanSeconds":3600}}}
This gets replicated to the secondaries, which check that renaming a system.buckets collection is not allowed and throw a fatal assertion:
