Hi Community,
I face below error while searching in a window in test environment, please help how to resolve this.

Things I have done:
- Cross checked every permission set with prod of user where this error is not present.
- checked Every check box of API( API in system info) is checked in in new permission set window
details of error message:

Thanks in advance.
If you get such issue in future, kindly try the steps that I mentioned above as well (If you cannot figure out the exact error). Those steps can be used if there are no known errors with user sessions in the Database end but in the IEE.
