Validation Error

Validation Failed

Problem type

validation-error

Type URI

https://docs.telebugs.com/rest-api/problems/validation-error

Status code

422 Unprocessable Content

Reasons

The server understood the request but could not process it because the payload failed validation.

This typically happens on POST, PATCH, or other mutating requests when one or more fields are:

• Missing or empty when required
• Of the wrong type or format
• Violating uniqueness or other domain constraints

Remedy

Read the errors extension in the response. It is a map of attribute names to arrays of validation messages.

Fix the invalid fields and resubmit the request.

  "errors": {
    "name": ["can't be blank"],

The errors object mirrors the structure returned by Active Model / Rails validations.
