Loopback Api Explorer Create Error: Invalid Date - node.js

Question

I´m using the API explorer of loopback to create a model with the following parameters:
{
"name": "string",
"last_name": "string",
"phone": 0,
"is_invited": true,
"realm": "string",
"username": "string",
"credentials": {},
"challenges": {},
"email": "string",
"emailVerified": true,
"status": "string",
"created": "2016-06-03",
"lastUpdated": "2016-06-03",
"id": 0
}
However, The server is always returning a 500 invalid Date error:
{
"error": {
"name": "Error",
"status": 500,
"message": "Invalid date: Invalid Date",
"stack": "Error: Invalid date: Invalid Date\n at DateType }
}
This is my model for reference. It inherits the User model of Loopback.
{
"name": "ExeboardUser",
"base": "User",
"idInjection": true,
"options": {
"validateUpsert": true
},
"properties": {
"name": {
"type": "string",
"required": true
},
"last_name": {
"type": "string"
},
"phone": {
"type": "number",
"required": true
},
"is_invited": {
"type": "boolean",
"required": true
}
},
"validations": [],
"relations": {
"boards": {
"type": "hasMany",
"model": "Board",
"foreignKey": "exeboardUserId",
"through": "ExeboardUserBoard"
}
},
"acls": [
{
"principalType": "ROLE",
"principalId": "$everyone",
"permission": "ALLOW",
"property": "logout"
}
],
"methods": {
}
}
Can anyone tell me what´s the problem with the date? I think it is correctly formated because it´s the default parameters that the explorer generates.

Answer 1

Don't know if you are interested in the answer, but I recently started working with loopback and got the same error as you, the date format that was accepted by the server is like this 2017-01-06T23:58:10.000Z
Hope it helps someone.
Ps.: if the date is not required by the model, don't even send it, not even with "null" or "" value, it will throw a 500 status error.

The correct date format is : 2017-10-12T10:31:37.925Z
And If you want to add fields of dateCreated and dateUpdate, Then use date mixin loopback-ds-timestamp-mixin
Install mixin with
npm i loopback-ds-timestamp-mixin --save
Add the mixins property to your server/model-config.json:
{
"_meta": {
"sources": [
"loopback/common/models",
"loopback/server/models",
"../common/models",
"./models"
],
"mixins": [
"loopback/common/mixins",
"../node_modules/loopback-ds-timestamp-mixin",
"../common/mixins"
]}
}
And in your model:
{
"name": "ExeboardUser",
"base": "User",
"idInjection": true,
"options": {
"validateUpsert": true
},
"mixins": {
"TimeStamp" : true
},
"properties": {
"name": {
"type": "string",
"required": true
},
"last_name": {
"type": "string"
},
"phone": {
"type": "number",
"required": true
},
"is_invited": {
"type": "boolean",
"required": true
}
},
"validations": [],
"relations": {
"boards": {
"type": "hasMany",
"model": "Board",
"foreignKey": "exeboardUserId",
"through": "ExeboardUserBoard"
}
},
"acls": [
{
"principalType": "ROLE",
"principalId": "$everyone",
"permission": "ALLOW",
"property": "logout"
}
],
"methods": {
}
}

When dealing with stringified params you should send the date value as a string in simplified extended ISO format in your query filter.
Here is an example of how you can do this in a very simple way using toISOString method:
const dataValue = new Date('10 May 2018 19:30 UTC');
console.log(dataValue.toISOString());
// output: 2018-05-10T19:30:00.000Z
