In REP-4527, we are hitting a fatal assertion:
[j7:cl1:n1] | 2024-05-15T21:37:17.404+00:00 I STORAGE 20276 [BackgroundSync] "openCatalog: reopening all databases" [j7:cl1:n1] | 2024-05-15T21:37:17.409+00:00 I STORAGE 20277 [BackgroundSync] "openCatalog: updating cached oplog pointer" [j7:cl1:n1] | 2024-05-15T21:37:17.422+00:00 F ASSERT 23095 [BackgroundSync] "Fatal assertion","attr":{"msgid":31179,"error":"UnsupportedFormat: Index: {name: x_1, ns: test.transactions_write_conflicts_unique_indexes} has incompatible format version: 8","file":"src/mongo/db/storage/wiredtiger/wiredtiger_index.cpp","line":742}
I believe it is caused by this command, which occurs right before a stepdown cycle:
[j7:cl1:n1] | 2024-05-15T21:37:12.232+00:00 I COMMAND 5324200 [conn359] "CMD: collMod","attr":{"cmdObj":{"collMod":"transactions_write_conflicts_unique_indexes","index":{"name":"x_1","forceNonUnique":true}}} [ClusterToClusterReplication:job7] 21:37:13.541Z Waiting for thread0 to report state RUNNING (after REVERSING) [CyclicStepdown:job7] 21:37:13.755Z The last stepdown for this replicator process was 13.5 seconds ago.
