Capture a parameter from an annotated training phrase

[anonymous]

When the user input is

“I want to order a new project called SalesPitch”

I want Dialogflow CX to determine that the intent is to order a new project, and also to capture the text “SalesPitch” in a parameter called projectName. I created a custom entity type for the project name, a regex, called projectNameText, and created a training phrase:

“I want to order a new project called Annabel”

and I annotated the training phrase so that Annabel was labelled as a projectNameText entity, all in the DialogFlow-CX console, as described in the documentation. But that instantly creates a parameter with Parameter id projectNameText. And I cannot edit that Parameter id. I can’t require that when Dialogflow matches that training phrase and extracts an entity of type projectNameText, it puts it into the parameter projectName. Dialogflow demands that it goes into a parameter called projectNameText, or projectNameText1 if there is more than one. When I run the simulator and type input that matches that training phrase, Dialogflow does indeed correctly extract the entity, but will only create a parameter named projectNameText - I can see the name and value in the simulator.

This StackOverflow answer implies that I can send the matched entity into any parameter I want. That would be sensible. But how do I do it? I can’t find any way to edit the parameter name in the Intent editor. All it gives me is this:

and I cannot change the Parameter Id.

I must be missing something really basic. Hints, please?

I asked this same question on StackOverflow but very few people read it so I am trying again here.

It is indeed not possible to edit the Parameter Id in the Intent Editor directly.

Instead, in the Intent Editor from the Build tab, accept the default Parameter Id, and Save the modified intent.

Then go to the tabs on the left of the Dialogflow CX console and choose the Manage tab. Choose Intents from the menu and find the intent you have just edited from the menu. Click the intent name to be given a different version of the Intent Editor. Same fields, same data, different functionality. In this different Intent Editor, click the Parameter Id you want to edit. It is now editable. Do not forget to hit Save after editing it.

From start to end, that took thirteen days to find. I posted here and received no answer. I finally subscribed to Google Cloud paid support and raised a support case and was given the answer in a video call with Google India. Perhaps it should be in the Google Documentation.
