Error 500 when converting subtask to issue

[Szymon Sobczak]

Hi, I'm using Jira Software. Whenever I try converting subtask to an issue, I gen a non-descriptive "500 - internal server error".

I'm the project admin and I should have all the permissions. This happens across multiple different subtasks.

Can anyone suggest what should I check for?

Looks like this is a permission issue. 
We got it to work after enabling this...

Schedule Issue (Ability to view or edit an issue's due date)

Hello @Szymon Sobczak

Welcome to Atlassian Community!

Per your description, I understand you are facing an error when you click in "Move" and try to convert your sub-tasks to issues. Is that correct?

Can you please confirm if the sub-tasks you are facing this problem are in a Next-gen project?

Investigating a little further, I found the following bug reported about your error, reproducible only in a Next-gen project:

- Converting a Sub-task of a Next-gen project to issue results in error 500 

If you are using a Next-gen project, please check if the following workaround works for you:

1 - Navigate to your project > Project settings > Issue types > Enable the Story Issue type

2 - Navigate to your sub-task > Convert it to a Story issue type. You will face the same error, however, the sub-task will be properly converted

3 - Change the story to the issue type you want

In case you are not in a next-gen project, please provide us with a screenshot of how you are trying to convert your issues with the generic error you are receiving.

Hi, it's been a while and I've stumbled upon this bug again.

Last time I just manually deleted all the subtasks and created new issues, but this messes up the reports.

I'm not using a next-gen project, this is in a classic one.

This is what I'm doing:

Step 2:

(the same error happens for all issue types I can select)

And the error:

Hi everyone,

May be an update on this one ?

We're getting the same error, It also happen trying to convert between Standard issue types.

Hello, we've also discovered this bug. 

Im curious to know if anyone else sees the permission showing as granted via their permission checker? We do, but the group condition fails (the overall status for the permission is granted). 

Is it possible the group condition is causing a bug that interferes with this operation?

I too am getting this bug. It's an old project and I'm not an admin on it, but admins seem to be able to do it for me (convert to an issue)!

I am also experiencing this bug.

I'm also getting this. I'm not admin, maybe that's why, but the error message is not very intuitive in that case.

A user must have the Schedule Issue permission in order to convert from a sub-task to another issue type and vise-versa.
