Hi all, my flow parses textual data using a template and GET method, however I am unable to post the result programmatically as a JSON. I want it to be generic and simple, without using scope.send or the 'form' method - and still be able to receive the results as msg.payload with the http request n…

Here is a working flow Use CTRL+I to import it. [{"id":"089792404c9ee4b8","type":"function","z":"a55f8f0f93e84992","name":"get patient summary","func":"const dicomFileAsBuffer = msg.payload;\n\ntry {\n const dataSet = dicomParser.parseDicom(dicomFileAsBuffer);\n const patient = {\n mo…

What do you see when you press the inject?

I see the template node raw code, instead of the expected result when I go to the "/dwvparser1" endpoint.

It looks like you did not export all of the http in nodes -- here is the error message I see: [image] The http request node is trying to POST to http://localhost:1880/dwvparser1 -- is that endpoint supposed to be another node-red flow endpoint?

so your end goal is to get the data back and not to create a new url endpoint /dwvparser1 ? in that case do an http request directly to your dcm url I experimented a bit with an npm dicomParser library ( link ) Node-red gives the ability to load external libraries using the functionExternalModules …

Hi i think you are confused with how things like this works. The inject you have calls the HTTP Endpoint then your template is returned. In your template I can see you have some html fragment and some scripts. These would normally be executed in a browser. The HTTP Request simply goes off to a re…

@UnborN @Steve-Mcl I appreciate your help. It's working!
