Error installing add-on: "The app defined an unknown module (confluenceContentProperties)

We are attempting to install an Atlassian Connect Express addon into our Confluence cloud space, and we are getting an error

We have previously installed this addon successfully into a different Confluence cloud instance.

I’m not sure where to begin troubleshooting this; are there potential differences between Confluence Cloud instance configurations that could be playing a role?

Hi @nathansmith,

You could try using the Atlassian Connect Validator to check your app descriptor.

Thanks Dugald. I was not familiar with that tool.

My App Descriptor validated successfully, however, so it wasn’t able to help me diagnose the issue.

Hi @nathansmith,

I just ran a test and was able to install an app with a confluenceContentProperties module. Are you able to provide any more details to help investigate this?

Dugald
