Connecting to Cognex 3D Scanner

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.
