A Request has been Terminated Message on Custom screen

Hello @Giri K 

it does look like the request is exceeding the licensing limits of some sorts. E.g. SQL query size, or nbr of SQL queries.

Hi @Giri K  were you able to find a solution? Thank you!

We noticed this error recently in our client’s 2023 R1 instance.  Wondering what the end result was here.

Getting this on an API call intermittently also

Denial Code 527- The operation was cancelled because a client was disconnected. Contact your provider for further assistance. CorrelationID: 8DDA3859164701D; Timestamp: 2025-06-04T16:33:42.1734941Z
