REST Step POST Flow Designer Error

[Rachna S]

Hello All,

We are getting the following error on making a Post REST call to certain endpoints-

Operation(Failed Delink Request Monitoring Subflow.ef25c0cbdb0ae0106e556e8cd396195b.a62540cbdb0ae0106e556e8cd396190c) failed with error: com.snc.process_flow.exception.OpException: Request not sent to uri= http://XXXX : java.net.ConnectException: Connection timed out (Connection timed out)

Hi,

Is this happening always or sometimes?

Hi Ankur,

We have 4 different endpoints and this happens with 2 out of 4. And it happens every time with those endpoints.

The others work fine.

@Rachna S 

you can try to increase the timeout property value

you can try increasing the timeout for Outbound REST.

• Property: glide.http.outbound.max_timeout
• Description: Specifies the number of seconds that RESTMessageV2 and SOAPMessageV2 APIs wait for a response from a synchronous call. The maximum value is 30 seconds.

How to increase the timeout for a REST response? (ECCResponseTimeoutException)

https://hi.service-now.com/kb_view.do?sysparm_article=KB0694711

Another method is while you are consuming the Rest message using script you can use this method

setHttpTimeout(Number timeoutMs)

Hi Ankur,

Thank you for your response. However I am using flow designer to make a REST call. Any advise on how I can add timeout or waitfor function in a flow designer please ?
