Custom REST connector with Asynchronous Pattern enabled is not working with On-premises gateway

(0) ShareShare
ReportReport
Posted on by illya13 11

Given:
- we have private REST service

- we installed and configured On-premises gateway

- we created Custom REST Connector

- everything works fine without usage of Asynchronous Pattern

 

When:

- we tried to enable Asynchronous Pattern

- and our long running operation returned 202 and location header

 

Then:

- Power Automate failed

- with an exception "The host name '10.1.xx.xx' resolved to IP address '10.1.xx.xx' which is restricted."

    To whom it may concern,

     

    to avoid this issue you also need to configure another endpoint in Custom REST Connector

    that matches the URL for status endpoint returned in location header

    and enable On-premises gateway in this endpoint.

     

    In this case Custom REST Connector will use On-premises gateway

    and will correctly route private IPs like 10.1.xx.xx

    Thanks for reporting this issue!

    Looks like an issue on how the Location header is translated and a gap in our platform.

    We also are not able to configure polling `trigger` with On-premises gateway
