[system test] Rebalance exited with reason {unexpected_exit, {upr_wait_for_data_move_failed, ...{error,no_stats_for_this_vbucket}}}}

rebalance 3+1 node on destination cluster

seen the same stack in MB-10936(couchbase-bucket team) but in my case I don't see (upr_add_stream) vbucket = 0 opaque = 0x20 status = 0x23 (rollback) in logs so don't know whose this issue

Rebalance exited with reason {unexpected_exit,
