Sync API.AI entities from firebase database - firebase

Question

I am building a bot for food ordering. I have saved my food categories (i.e Starters, Meals, Fish, Meat, Pasta etc) in firebase and every food-category can have multiple food-items.
here is my food-item structure in firebase
{

"food_price" : 45,
"food_url" : "https://i.scaley.io/768x687/lebijou.io/_jamesapp/food/airhomeCHZH3/FISH/Homemade fish sticks.jpg"

What I am trying to achieve is to sync my food-items (under food categories) from firebase to api.ai entities.
I have done it manually on api.ai like below
http://prntscr.com/fhpme6
Now want to do all this via code (nodejs)
I know there is api.ai provides apis to play with entities i.e https://docs.api.ai/docs/entities (I have used them)
I can extract food-items from firebase and sync data to api.ai entities. But there is a problem. I can't overwrite and/or delete the entities already used in my intents.
Here is the code I have tried so for FoodSync.js
var util = require('util');
var exec = require('child_process').exec;
var apiai_developer_access_code = "e764e24fa51e4d93bdc1e6bde92d07d8"
class FoodSync {
syncFood(firebaseRef, apiAiRef, callback){
//Retrieves a list of all entities for the agent.
var all_entities = 'curl -k -H "Authorization: Bearer '+apiai_developer_access_code+'" "https://api.api.ai/v1/entities?v=20150910"'
var food_category_id = "";
var all_entities_array = [];
var all_food_cat_names = [];
var all_food_cat_entities_id = [];
var that = this;
that.execCommand(all_entities, function(error, stdout, stderr){
var jsonResponse = JSON.parse(stdout)
all_entities_array = jsonResponse;
for(var i = 0; i < jsonResponse.length; i++) {
var entity = jsonResponse[i];
if(entity.name == "food-categories"){
food_category_id = entity.id;
break;
}
}
console.log('food_category_id: ' + food_category_id);
if(food_category_id == ""){
return;
}
var food_category_entity_url = that.getEntityUrlWithID(food_category_id);
console.log('food_category_entity_url: ' + food_category_entity_url);
that.execCommand(food_category_entity_url, function(error, stdout, stderr){
var jsonResponse = JSON.parse(stdout)
console.log('food_category_entity: ' + JSON.stringify(jsonResponse));
var food_cat_all_entities = jsonResponse.entries;
console.log("food_cat_all_entities : "+ food_cat_all_entities.length);
for(var i = 0; i < food_cat_all_entities.length; i++) {
var food_cat_entity = food_cat_all_entities[i];
var food_cat_entity_name = food_cat_entity.value.replace('#', '')
console.log("food_cat_entity_name : "+ food_cat_entity_name);
console.log("all_entities_array.length : "+ all_entities_array.length);
for(var j = 0; j < all_entities_array.length; j++){
var entity_check = all_entities_array[j];
if(entity_check.name == food_cat_entity_name){
all_food_cat_entities_id.push(entity_check.id);
}
}
// Here I got all food-entities id.
console.log('all_food_cat_entities_ids: ' + all_food_cat_entities_id);
// Here I am calling the DELETE entity first (then Recreate), Problem is my entity is used in My some of Intents, So upon delete I am getting the error,
// {
// "id": "09e2c21d-b4e3-4a34-a774-eab781c957e1",
// "timestamp": "2017-06-09T10:01:19.294Z",
// "lang": "en",
// "status": {
// "code": 400,
// "errorType": "bad_request",
// "errorDetails": "Some entity names are in use: food-cat-fish"
// }
// }
}
})
// if(error !== null){
// console.log('exec error: ' + error);
// callback()
// }
})
}
getEntityUrlWithID(entitiy_id){
// Retrieves the specified entity.
var entities = 'curl -k -H "Authorization: Bearer '+apiai_developer_access_code+'" "https://api.api.ai/v1/entities/'+entitiy_id+'?v=20150910"'
return entities;
}
execCommand(command, callback){
console.log('execCommand: called');
exec(command, function(error, stdout, stderr){
//console.log('stdout: ' + stdout);
//console.log('stderr: ' + stderr);
if(error !== null){
console.log('exec error: ' + error);
}
callback(error, stdout, stderr)
});
}
