  • 1.  App Connect - Callable flow not working (Error: ESOCKETTIMEDOUT)

    Posted Thu January 20, 2022 06:57 PM
    Hello,

    While trying to invoke a callable flow from within one of the integration flows I am building on IBM App Connect Cloud, I am getting the error (Error: Error: ESOCKETTIMEDOUT) when clicking on Try this action.

    If I run the flow, I see this error message in the logs:
    The Callable flow Invoke action failed to execute the custom action.

    Before reaching to this, I connected callable flow using App Connect cloud console and then I downloaded the agentx file. The flow appears in the callable flows and on premise server log shows successful connection.

    There is no indication in the on premise App Connect that there is an attempt to call the callable flow.

    Can anyone help me in troubleshooting or resolving this issue?

    Thanks,
    Moayyad

    Are you trying to call between servers or within a server?

    If between servers, could there be a firewall between them preventing the connection?  That error seems fairly low-level to me....

    (I see it has been 12 days since you asked; if you have resolved it, please respond with the cause and fix.)

    Regards, T.

    It is between servers, a call from IBM Cloud App Connect to a callable flow to IBM App Connect on-premise. 


    The issue isn't resolved yet. Initial connection between IBM Cloud App Connect (Callable flow and Agent connect test) shows successful connection and server callable flow appears in the list.



    However, when the flow is run, this is the error that appears in logs of IBM Cloud App Connect: The Callable flow Invoke action failed to execute the custom action. While try this action inside the flow editor shows this error: Error: ESOCKETTIMEDOUT.

    ESOCKETTIMEDOUT means you never got a response back, so still could be firewall/proxy/etc. between the servers not playing nicely, or maybe even that the callable flow actually isn't returning anything.  Could also be a too-short timeout waiting for that response.  Googling ESOCKETTIMEDOUT shows a lot out there, nothing specific for App Connect that I saw however, but all of the ones I looked at tended to mention one or more similar things to these.
