It can be a lot of things. Can you provide any more information? Logs?

@Arvinder Bhalla : There was a similar case discussed @ https://www.outsystems.com/forums/discussion/69148/service-center-errors-and-data-is-not-retrieved/ back in 2021. However there is no solution on that discussion.  You may please share any additional information as suggested by @Nuno Reis.

In the meantime please reach out to OutSystems support for a resolution.

Thank you Nuno and Siya. The log files do not have any more information except the error message.

No errors in the database.yes, the aggregate executes successfully and returns data as well.

Hello @Arvinder Bhalla,
 
Please check if this process starts from a screen or client action. I have encountered a situation where the request began from a screen action and received an error pattern similar to what you described.

Screen and client actions in React should have a timeout of 10 seconds, and since your call takes longer, it will be interrupted.

You mentioned that you have already increased the timeout of the aggregate, but I believe the issue might be with the screen action. Try implementing that logic in a data action, which can indeed have more time to execute its process.

Best regards, 

Thank you, let me try moving my logic to data action and see.

Hi, did this solve your issue?

Not yet, tried multiple things but still experience the error. Working with Outsystems support on it.
