Hi @herbdool - I am running into the same problem. I see that you haven't had much luck getting your changes merged in the webform_civicrm module. I was wondering if you figured out a way to address this problem?

@jmcclelland I had added my patch to the composer file for the website. But now that it's all migrated don't need the patch. Still it's a shame that they won't merge it. Maybe you can chime in on the issue.

@jmcclelland in particular test this PR colemanw/webform_civicrm#894

@herbdool Thanks for the follow up - I'll definitely chime in. But... how did you disable the webform_civicrm handler just for submission imports? In this ticket you reference hook_webform_handler_invoke_alter(\Drupal\webform\Plugin\WebformHandlerInterface $handler, $method_name, array &$args) but I'm still trying to wrap my head around how to use that hook to disable the handler just for migrating submissions.

I think I ended up not using that hook. I just disabled the handler manually for each webform. It can be disabled in the UI or by changing the yml file for the webform and importing config changes.

Thanks so much for the feedback. I think I sorted out the hook code and submitted a PR. I'll also follow up on the webform PR.
