Add Parameters to EventInput on QueryInput for DialogFlow Java API

Question

I'm trying to set parameters inside my EventInput object, in order to send it inside my QueryInput and detect the Intent. I'm using DialogFlow V2Beta1 API for Java version com.google.cloud:google-cloud-dialogflow:0.85.0-alpha. I'm aware of the json expected format based on
Custom Events documentation, but all method available didn't work for me. Related question for other languages didn't awnser it either: set parameters in EventInput in Dialogflow V2 API. I'm losing something about protobuf pattern? My parameters are the following:

I've already tried the below code, but it doesn't work, the response from server always asks "What is the location_user?", meaning that the parameter is missing. On DialogFlow V2 happens the same issue.

queryInput = QueryInput.newBuilder()
                        .setEvent(
                                EventInput.newBuilder()
                                        .setName("REVISION")
                                        .setParameters(
                                                Struct.newBuilder()
                                                        .putFields("location_user",
                                                                Value.newBuilder()
                                                                        .setStringValue("Campinas")
                                                                        .build())
                                                        .build()
                                        )
                                        .setLanguageCode(config.getLanguage()
                                        )
                        )
                        .build();

output json:

name: "REVISION"
parameters {
  fields {
    key: "location_user"
    value {
      string_value: "Campinas"
    }
  }
}
language_code: "pt-BR"

I also have the same question as Subin: how to pass a parameter in a QueryInput object when calling detectIntent()? — Terry, Jan 26 '20 at 20:36

Your code seems to be correct. The problem is in your Intent configuration.

from dialogflow docs:

To reference an event parameter in the parameter table or a response, use the following format: #event-name.parameter-name.

In your example: put #REVISION.location_user in Value column in Parameters table.

I've checked your code and it works, please find my Intent configuration below

Thanks for your help, but IMHO that's not the problem. When I try to detect my Intent, the response from server always asks "What is the location_user?", meaning that the parameter is missing. – Raphael Adamski Apr 05 '19 at 11:25
As in edited answer - I've checked your code and it works. I've attached screenshot of sample Intent configuration I've used. – MortFollower Apr 05 '19 at 11:50

@SubinBabu I think this is separate topic. More details about your case would be needed. Nevertheless, if you use IntentAPI you can just create new parameter in context when you call Dialogflow. – MortFollower Jun 25 '19 at 06:22
