Hi @MauryZapata ,
Happy that the solution our team provided helped your case.
I am responding to a resolved thread, just to bring to your and any other future reader’s notice that the App migration platform notifies your cloud app with a listener-errored web hook event if your server app threw an exception from onStartAppMigration.
Here’s the link to the public blog we did about this sometime back, https://community.developer.atlassian.com/t/oh-what-why-is-my-app-migration-looking-stuck-for-a-long-time-has-something-gone-wrong-on-the-server-side/63217 .
Thanks,
Hariharan.
