ValidationException

Errors in schema validation.

Implements: BadRequestException

Description

The ValidationException is used to define errors in schema validation.

Important points

  • Validation errors are usually generated based in ValidationResult.
  • If using strict mode, warnings will also raise validation exceptions.

Constructors

Creates a new instance of validation exception and assigns its values.

ValidationException(context: Optional[IContext], message: Optional[str], results: List[ValidationResult])

  • context: IContext - (optional) a context to trace execution through a call chain.
  • message: Optional[str] - (optional) a human-readable description of the error.
  • results: List[ValidationResult] - (optional) a list of validation results
