Manage validation errors in the body of requests

Whenever a validation error happens in the body of one of your requests, the same error message format will be returned:

{  
  "statusCode": 400,  
  "timestamp": "2024-07-12T05:59:48.327Z",  
  "path": "/api/auth/signin",  
  "errors": \[  
    {  
      "target": {},  
      "property": "email",  
      "children": \[],  
      "constraints": {  
        "isEmail": "email must be an email"  
      }  
    },  
    {  
      "target": {},  
      "property": "password",  
      "children": \[],  
      "constraints": {  
        "isLength": "password must be longer than or equal to 6 characters",  
        "matches": "password must match /^(?=._[a-z])(?=._[A-Z])(?=.\*[0-9])/ regular expression",  
        "isString": "password must be a string"  
      }  
    }  
  ],  
  "message": "email must be an email",  
  "name": "REST_VALIDATION_ERROR"  
}

In the errors array, you will find a list of all the keys for which the validation rules broke. Inside of the errors object, you will find under constraints the rule that must be respected.
