Creating entites in Dialogflow using Node.js

I'm trying to create entites in Dialogflow using node.js. The entity values will come from a JSON file. I'm currently testing it using postman. However, the entity values are not being separated and being combined in only one line. How do I fix this? Thank you

This is my sample JSON file that is being sent.

     {
"Entity_Values": [
    {
    "Value": "One",
    "Synonym":["Solo","1"]},
    {
    "Value": "Two",
    "Synonym":["Double","2"]}
    ],
"Entity_Name": "Sample"}

This is what I have so far:

function createEntity (inputEntityobj, EntityName) {
 const promises = [];
 let entity_values = {value:[], synonyms:[]};
 let inputEntity_values = [inputEntityobj];

 for (i = 0; i < inputEntityobj.length; ++i) {
  let inputEntity_values = [inputEntityobj[i].Value];
  let inputEntity_synonym = [inputEntityobj[i].Synonym];
  entity_values.value.push(inputEntity_values);
  entity_values.synonyms.push(inputEntity_synonym);
 }

 const sizeRequest = {
 parent: agentPath,
 entityType: {
  displayName: (EntityName),
  kind: 'KIND_MAP',
  autoExpansionMode: 'AUTO_EXPANSION_MODE_UNSPECIFIED',
  enableFuzzyExtraction: true,
  entities: [entity_values],
 },
 };

This code outputs

value: [ [ 'One' ], [ 'Two' ] ], synonyms: [ [ [Array] ], [ [Array] ] ]

And in Dialogflow, these are all in one entity entry instead of being in two separate entries.

Your JSON input is almost identical to the required object format for entities (reference) and will only need a little bit of tweaking to make it work. Using your JSON, I renamed the Value and Synonym to value and synonyms. Loop through Entity_values and push the key value pair to list entityVal and use it for the request.

'use strict';

const dialogflow = require('@google-cloud/dialogflow').v2;

var inputEntityObj =      {
"Entity_Values": [
    {
    "Value": "One",
    "Synonym":["Solo","1"]},
    {
    "Value": "Two",
    "Synonym":["Double","2"]}
    ],
"Entity_Name": "Sample"};

var obj = inputEntityObj['Entity_Values'];

// rename keys
var res = obj.map(item => {
  item.value= item.Value;
  item.synonyms= item.Synonym;
  delete item.Value;
  delete item.Synonym;
  return item;
});


var entityVal =[];
for (const entity in res){
        entityVal.push(res[entity]);
}

var projectId = 'your-project-id';
var entityType = { displayName: 'test', //hard coded value for testing purposes
        kind: 'KIND_MAP',
        autoExpansionMode: 'AUTO_EXPANSION_MODE_UNSPECIFIED',
        enableFuzzyExtraction: true,
        entities: entityVal,

};

var parent = `projects/${projectId}/agent`;
var request = { parent: parent,
        entityType: entityType
};

console.log(JSON.stringify(request, null, 2));

const client = new dialogflow.EntityTypesClient();
client.createEntityType(request);

See testing done below:

request structure:

{
  "parent": "projects/your-project-id/agent",
  "entityType": {
    "displayName": "test",
    "kind": "KIND_MAP",
    "autoExpansionMode": "AUTO_EXPANSION_MODE_UNSPECIFIED",
    "enableFuzzyExtraction": true,
    "entities": [
      {
        "value": "One",
        "synonyms": [
          "Solo",
          "1"
        ]
      },
      {
        "value": "Two",
        "synonyms": [
          "Double",
          "2"
        ]
      }
    ]
  }
}
