HTTP Code 500: Sequence contains no matching element

(0) ShareShare
ReportReport
Posted on by 5

I have exposed pages via web service, but when accessing them via Postman, I at times face the error "Sequence contains no matching element", with http code 500 - for internal server error.

When this occurs, I have to wait for close to 3 hours for the error to disappear, even though I am still able to access the sandbox from BC without any hitch. I have tried restarting the environment from the admin center, but the error persists.

NB: All works fine with the exposed pages and postman, but the error appears from nowhere - making it not possible to access the pages via postman.

I am using BC version 21.

Anyone has come across such a challenge? Kindly share the solution.
