ValidationException

Class

The request failed because one or more input parameters don't satisfy their constraint requirements. The output is provided as a list of fields and a reason for each field that isn't valid.

The possible reasons include the following:

• UnrecognizedEntityType

  The policy includes an entity type that isn't found in the schema.

• UnrecognizedActionId

  The policy includes an action id that isn't found in the schema.

• InvalidActionApplication

  The policy includes an action that, according to the schema, doesn't support the specified principal and resource.

• UnexpectedType

  The policy included an operand that isn't a valid type for the specified operation.

• IncompatibleTypes

  The types of elements included in a set, or the types of expressions used in an if...then...else clause aren't compatible in this context.

• MissingAttribute

  The policy attempts to access a record or entity attribute that isn't specified in the schema. Test for the existence of the attribute first before attempting to access its value. For more information, see the has (presence of attribute test) operator in the Cedar Policy Language Guide.

• UnsafeOptionalAttributeAccess

  The policy attempts to access a record or entity attribute that is optional and isn't guaranteed to be present. Test for the existence of the attribute first before attempting to access its value. For more information, see the has (presence of attribute test) operator in the Cedar Policy Language Guide.

• ImpossiblePolicy

  Cedar has determined that a policy condition always evaluates to false. If the policy is always false, it can never apply to any query, and so it can never affect an authorization decision.

• WrongNumberArguments

  The policy references an extension type with the wrong number of arguments.

• FunctionArgumentValidationError

  Cedar couldn't parse the argument passed to an extension type. For example, a string that is to be parsed as an IPv4 address can contain only digits and the period character.
