I am trying to take an output from a Cognex 3D-L4100 scanner and parse it through a Node-RED flow to an HTTP response node. The debug node shows the response output, however the HTTP node shows a "No response object" message in the debug window. Has anyone had a similar issue and if so, were you able to resolve it?

Hi, welcome to the forum.

You post is not 100% clear to me. Is the cognex scanner calling a `http-in` node endpoint?

Can you show us a screenshot of flow and these messages?

Assuming you are creating an endpoint, can you double check that the message generated by the `http-in` node makes its way back to a `http-response` node and that it has the original `msg.req` and `msg.res` properties?

Essentially, make sure you are not deleting extra properties of the incoming http `msg` object and that they make it all the way back to the http-response node.

This is touched on in the http-in nodes built-in help.
