Interesting, that suggests a very broken add-on, but possibly a system one.  Do you know which area of JIRA this is happening in and what you were expecting to be there instead of the error?

Ok, there's something wrong with the issue view module in JIRA Software.  It might be an add-on breaking it, but the error does suggest it's inside Software.

Could you check the logs - ideally, have the application log open and tailing, so you can see it real-time, then click to provoke the error and see what goes into the log at the time.  Also, check Admin -> manage applications and check if there's any errors flagged there.

Hi Nic

Here's the log for you to know, thank you.

Ok, the only way I can think you can get that error is if you've got an invalid version of the Agile add-on installed - incompatible with your version of JIRA.

What versions are you using here?  JIRA and Agile, or JIRA Software?

Same here. Apparently, appeared after the upgrade to JIRA Software 7.2.3

Hi Nic

I am using JIRA 7.2.3 in my software smile

Oh hi SVP were in the same problem.


Hey Nic,

upgraded to JIRA Software 7.2.3 a few days ago and now having the same problem...


Ok, svp - you might want to check that the version of the drag-and-drop add-on is correct - update it if you have the option.

For the rest, it seems there's a bug in JIRA Software 7.2.3, or its interaction with an add-on - I'd encourage you all to raise it directly with (and svp if the drag and drop add-on is up to date)

This is already resolved on my part by removing the add-on plug in PSD Preview Plugin by ALM Works.

Indeed, in my case JIRA Drag and Drop Attachment Plugin was disabled for an unknown reason. After re-enabling the issue gone. Thanks @Nic Brough [Adaptavist] for a hint.

I'm seeing the same issue as Stacy. When I disable PSD Preview plugin, the error goes away.

Nicely found - the PSD Preview plugin is the problem for most cases.

Enabling the disabled sytem JIRA Drag and Drop Attachment Plugin fixed my problem as well.  Was getting "delegated panel with the complete key must be an instance of WebPanelModuleDescriptor" errors after upgrade from 7.2.1 to 7.4.1.

Hi all,

Thanks for bringing our attention to this problem. This is in fact a bug in JIRA Software (JIRA Agile), which is being triggered by PSD Preview plugin.

But you can also reproduce this bug without PSD Preview – just go to the Add-on Manager and disable "attachmentmodule" module in "Atlassian JIRA - Plugins - View Issue Panels" system plugin. This is new to JIRA 7.2, this bug does not reproduce on JIRA 6.4. 

I've posted a support request to Atlassian (unfortunately, we can't post bugs directly now) -

We'll see what they say. Hopefully, it will be confirmed as a bug and fixed soon.

Meanwhile, there's a workaround without uninstalling PSD Preview – go to the PSD Preview configuration and switch to "Separate Panels" mode, so that PSD Preview does not hide the standard attachments panel.

Kind regards,
ALM Works

How to manage many similar workflows?

I have multiple projects that use variations of the same base workflow. The variations depend on the requirements of the project or issue type. The variations mostly come in the form of new statuses ...
