With the app details that you have provided over the private message thread, the Freshcaller team has got a chance to check this and informed their findings.
In the function’s
renderData() callback, it is expected for the app to include the
response attribute in the
data object as per the actions configuration expectations. But, it has been modified to
requiredResponse in your app.
This is the reason, the routing automation workflow cannot detect the response from the app.
Could you change this callback data and confirm if it works fine? Please refer to the documentation for the syntax for the callback method properties and response payload.
