      Failing unit-test task
      Project: wiredtiger-mongo-v7.0; variant: rhel8-zseries; WiredTiger commit: 1dfc1f84248394038b209cc32dfa6f71cf0b6f85.

      The task ended with 26 errors (1373 skipped). Its real failure is in test_util18.py:79: codecs.encode(key.encode(), 'hex') raises LookupError: unknown encoding: hex across test_printlog_file, test_printlog_hex_file, test_printlog_lsn_offset and test_printlog_message. The Build Baron extracted [UPDATE_ABORT] messages from test_rollback_to_stable22 are DEBUG_1 diagnostics, not the failing assertion.
