WAFInvalidParameterException

class WAF.Client.exceptions.WAFInvalidParameterException

The operation failed because AWS WAF didn’t recognize a parameter in the request. For example:

• You specified an invalid parameter name.

• You specified an invalid value.

• You tried to update an object ( ByteMatchSet, IPSet, Rule, or WebACL) using an action other than INSERT or DELETE.

• You tried to create a WebACL with a DefaultAction Type other than ALLOW, BLOCK, or COUNT.

• You tried to create a RateBasedRule with a RateKey value other than IP.

• You tried to update a WebACL with a WafAction Type other than ALLOW, BLOCK, or COUNT.

• You tried to update a ByteMatchSet with a FieldToMatch Type other than HEADER, METHOD, QUERY_STRING, URI, or BODY.

• You tried to update a ByteMatchSet with a Field of HEADER but no value for Data.

• Your request references an ARN that is malformed, or corresponds to a resource with which a web ACL cannot be associated.
