Hi,

From Power App, I am sending certain values to Master flow and from there I am calling child flow and sending the values.

But after clicking on the button on power app, values are being transmitted but I am getting the error as mentioned below

Please let me know to cross over the issue.

Regards,

Sudheer

Dataflows

You are hitting a 502 BadGateway with innerError NoResponse. Power Apps sent the request, API hub waited, your flow did not return a response in time. The parent flow is likely calling a long-running child flow or doing heavy Dataverse work before “Respond to PowerApp or flow.” I propose below steps to try and resolve. There is no quick or specific approach since you get to the root cause.

Most common cause in this case the parent waits for the child flow to finish, and the child takes too long.

Fixes

Return a quick response in the parent flow, then process heavy work in background.
Switch “Run a child flow” to Asynchronous.
Keep “Respond to PowerApp or flow” as the last step and always executed.
Optimize actions: reduce loops, keep payloads small.
