Error testing cron strings

Also seeing this error trying to run 'TestDo10ThingsOnCron'

TypeError: Cannot access offset of type array on array in Drupal\Core\Database\Query\Merge->key() (line 331 of core/lib/Drupal/Core/Database/Query/Merge.php).
Drupal\codit_batch_operations\Cron\CronManager->querySetCronTime() (Line: 635)

I found the problem

"Passing an array to the \$field argument of " . __METHOD__ . '() is deprecated in drupal:10.2.0 and is removed from drupal:11.0.0. See https://www.drupal.org/node/2205327', E_USER_DEPRECATED

I am kind of surprised Drupal Rector did not spot it.
