errors for unknown reasons

[Paul Franks]

Hi All - noob question - trying to create resources via ansible -> CFN and i get an error i can't understand

Failed to create stack pfranks-VPC: Parameter validation failed:\nUnknown parameter in input: \"ClientRequestToken\", must be one of: StackName, TemplateBody, TemplateURL, Parameters, DisableRollback, TimeoutInMinutes, NotificationARNs, Capabilities, ResourceTypes, RoleARN, OnFailure, StackPolicyBody, StackPolicyURL, Tags Parameter validation failed:\nUnknown parameter in input: \"ClientRequestToken\", must be one of: StackName, TemplateBody, TemplateURL, Parameters, DisableRollback, TimeoutInMinutes, NotificationARNs, Capabilities, ResourceTypes, RoleARN, OnFailure, StackPolicyBody, StackPolicyURL, Tags - <class 'botocore.exceptions.ParamValidationError'>.

of course there is no "ClientRequestToken" in my code...
