Major - P3 In BF-26341, the following can be observed in logs:
[js_test:resharding_coordinator_recovers_abort_decision] c20296| 2022-09-11T05:28:13.563+00:00 I REPL 21098 [BackgroundSync] "Starting rollback due to fetcher error","attr":{"error":"OplogStartMissing: the sync source's oplog and our oplog have diverged, going into rollback. our last optime fetched: { ts: Timestamp(1662874093, 2), t: 1 }. optime of first document in batch: { ts: Timestamp(1662874093, 4), t: 2 }. sync source's first optime: { ts: Timestamp(1662874088, 18), t: 1 }","lastCommittedOpTime":{"ts":{"$timestamp":{"t":1662874092,"i":42}},"t":1}}

This causes the test client disconnection and the command to turn off the failpoint fails. A fix here would be to wait for secondaries to be ready before doing so.
