Hello community.

I`m trying to create a custom object with API（ **POST** /crm-object-schemas/v3/schemas）

I get error when I specify property type “number” or “date”.（only “string” works fine.）

Please advise.

Thank you and best regards.

**error message**

Hi @kaoki Can you post your api request log ?

Same error here with property type “date” and “datetime”, using postman and testing from API docs:

HTTP 400

{  
“status”: “error”,  
“message”: “Unexpected property type ‘date’, expected one of: [string, object\_coordinates, json]”,  
“correlationId”: “21ef7877-b0cb-492b-a755-32ed9625b411”,

I also seem to not be able to create a custom object and set a required date/datetime field:

**Here is the request:**

var request = require(“request”);

var options = {

method: ‘POST’,

url: ‘[https://api.hubapi.com/crm/v3/schemas](https://api.hubapi.com/crm/v3/schemas)’,

qs: {hapikey: ‘YOUR\_API\_KEY’},

headers: {accept: ‘application/json’, ‘content-type’: ‘application/json’},

body: {

```
labels: {singular: 'Virtual Event', plural: 'Virtual Events'},

requiredProperties: \['virtual\_event\_title', 'virtual\_event\_date'],

name: 'virtual\_event',

primaryDisplayProperty: 'virtual\_event\_title',

properties: \[

  {

    name: 'virtual\_event\_title',

    label: 'Virtual Event Title',

    isPrimaryDisplayLabel: true,

    type: 'string'

  },

  {name: 'virtual\_event\_date', label: 'Virtual Event Date', type: 'date'}

],

associatedObjects: \['CONTACT', 'COMPANY'],

metaType: 'PORTAL\_SPECIFIC',

secondaryDisplayProperties: \['virtual\_event\_date','date']

```

},

json: true

};

request(options, function (error, response, body) {

if (error) throw new Error(error);

console.log(body);

});

**Response:**

{  
status: ‘error’,  
message: “Unexpected property type ‘date’, expected one of: [string, object\_coordinates, json]”,  
correlationId: ‘300fe4d9-3043-4c06-bacb-e6c46e55fc80’,  
category: ‘VALIDATION\_ERROR’  
}

Not sure if I’m doing something wrong or if there is a bug in the API or documentation.

I figured out the issue. The documentation on this page: [https://developers.hubspot.com/docs/api/crm/crm-custom-objects?\_ga=2.165441468.2023144461.1605542585-1624948680.1599571013](https://developers.hubspot.com/docs/api/crm/crm-custom-objects?_ga=2.165441468.2023144461.1605542585-1624948680.1599571013)

is missing the field property of [fieldType:'date] when you generate the example code.

This would be the whole request:

{name: ‘date\_property\_name’, label: ‘Date Property Label’, type: ‘date’, fieldType:‘date’}
