## Errors
<a name="API_BatchGetPolicy_Errors"></a>

For information about the errors that are common to all actions, see [Common Error Types](CommonErrors.md).

 ** AccessDeniedException **   
You don't have sufficient access to perform this action.  
HTTP Status Code: 400

 ** InternalServerException **   
The request failed because of an internal error. Try your request again later  
HTTP Status Code: 500

 ** ThrottlingException **   
The request failed because it exceeded a throttling quota.    
 ** quotaCode **   
The quota code recognized by the AWS Service Quotas service.  
 ** serviceCode **   
The code for the AWS service that owns the quota.
HTTP Status Code: 400

 ** ValidationException **   
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](https://docs.cedarpolicy.com/policies/syntax-operators.html#has-presence-of-attribute-test) 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](https://docs.cedarpolicy.com/policies/syntax-operators.html#has-presence-of-attribute-test) 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.  
 ** fieldList **   
The list of fields that aren't valid.
HTTP Status Code: 400
