Workaround:

Below are the list of options that we tried to resolve this issue:

• Checked Activities on Web Interface using same users (i.e. for e.g. “ABC”) credentials, but no error occurred when we open activities in Web Interface.
• Checked security roles of “ABC” user who was unable to open and getting error while accessing Activities in UCI App as well as for testing purpose provided “System Administrator” Role to that user, but even then issue not resolved.
• Cross checked Security roles with other User “XYZ” who is able to access “Activities” on UCI app and we noticed that User “ABC” also has the same security roles but even then he was getting above issue.

Solution:

After trying multiple options we observed that, Activities which are in Web Interface and had many views but no view was set as Default view(for that particular user who was facing this issue) i.e. not pinned up as shown in below screenshot.

So after logged in with that users credential we Pinned up view (i.e. set “My Activities”) as Default view as shown in below screenshot. Then went to UCI and refresh the page and Activities appeared on the app without throwing any error.

After refreshing the UCI app we were able to open activities using that users credentials who was facing this issue in UCI App earlier. As seen in the below screenshot.

Conclusion:

If there is no view set as “Default View” for Activities or any other entities in that case user may receive above kind of error on UCI app, so solution is set one view as Default View.
