Few MR reports are showing Service Error for some of the users while rest can access.

Summary:

We have a MR Report created for the Organization and everything was working fine during the development and demo.

We were editing few cosmetic changes and suddenly the report is not showing up in preview.

Here is the service error we are getting.

Few inputs on this issue.

1. We asked another developer to browse the same MR report. .. It worked fine for him and able to open the report with out error.
2. Here we assumed, it could be with browser cache or something, and then asked the user to clear cache and restart the laptop and try another browser to see if it is working. It didnt work after these activities and checks.
