Hi @Mark Marijnissen,


Did you use this form to submit your app to the marketplace? I just tried myself and didn’t face any issue. Could you try again and let me know if it works?

Yes! I tried again and still the same error.

Tried 2 browsers: Chrome & Edge.
No ad-blockers or other weird plugins.


Facing the same problem!

Hi @Mark Marijnissen@Bart Bongers,


Thanks for raising this issue. Our technical team is investigating the issues, I will come back to you as soon as I have more information.


Edit: The team might have found the issue. It seems that if you have more than 500 characters in any of the fields requested, the API crashes. They will work to fix this, but as a workaround you can submit your app if you use less than 500 chars.




I am facing the same issue.

I use less than 500 characters in every field.

The API call fails:

  "type" : "",
  "title" : "Internal Server Error",
  "status" : 500,
  "detail" : "Cannot invoke \"java.lang.Boolean.toString()\" because the return value of \"com.miro.marketplace.dto.mainapp.JiraTicketDTO.dataSentExternally()\" is null",
  "path" : "/api/marketplace-public/app-submissions",
  "message" : "error.http.500"
