Unable to process binding

Hello,

 

can't currently open my app in edit mode (the published version seems fine). The error code is

 

"Unable to process binding: attr: function() { return { title: properties.Tooltip, 'aria-label':accessibleLabel, 'ariadescribedby': descriptionId} }

 

Message: accessibleLabel is not defined"

 

How can I solve this error?

 

Thanks

I've had an update from the service team at MS.

 

Apparently this is a known issue and they are working on a fix. They have asked for more time.

 

I'll continue to update as I know.

 

Cheers

FYI for anyone. After logging a ticket with Microsoft, here are some of the root cause they have found so far.


Root Cause –

This issue is caused by creating an app on a newer version of Studio and then opening it on an older version of Studio.

To be more specific,

The app must have a Timer control
This can happen when app makers create an app in preview(Dev/Test/UAT) Studio and then try to open it in prod Studio. Prod is always older than Preview.
Fix and mitigation –

This issue is resolved in upcoming release.
As a mitigation, app makers can open their app with the latest version of Studio. All worldwide regions except Moderate should work. Remove all Timer controls if they wish to open it in an older version of Studio.
Expected behavior

Instead of crashing, users should see a dialog that informs them to use the latest version of Studio. They will still not be able to edit the app though, as there are backwards incompatible changes.

Microsoft support tell me that MS have deploy a fix for this issue today.

 

While on the phone I tested it but the issue was still there. We agreed to try again tomorrow, giving the fix a bit of time to propagate to all the various regions.

 

fingers crossed!

I have been asked to try logging into the app today and happily the error message is now gone. It seems MS have fixed it.

 

Thanks!
