Unable to open the CDS app

[Teresa24486]

Hi,

Strangely, I am unable to open all of my CDS app from a single environment or share it with the users. Anything wrong? This is the message:

Below is the exception error:

Hello @Teresa24486,

Not Sure my suggestion help you

1. Make Sure Logged in user have proper security Role

2. Make Sure Model Driven app have proper security Roles

If both of them not helping try raising Support Ticket to Microsoft to get it fixed.

Please mark as Answer if it is helpful and provide Kudos

Hi @rampprakash ,

Thank you for the suggestion. It was my browser cache that caused this issue. I cleared them and it worked as expected.
