ValidationErrorData

Which fields failed validation, and why.

issues
Type: array object[] …100

Every field that failed validation, up to 100 per response. Absent when the request was rejected for a reason other than validation — message says why.
- field
  Type: string
  required
  
  The field that failed, as a dotted path — listing.price.amount for a nested field, lines.3.quantity for the fourth entry of an array. Empty when the problem is with the request body as a whole.
- message
  Type: string
  required
  
  What is wrong with the value you sent.
