AWS DataPipeline via Cloudformation throws error 'type is not defined in fields'

Question

I'm trying to deploy the Export DynamoDB Table to S3 template via Cloudformation but getting a type is not defined in fields error from Cloudformation. I have a Key with the value of type for all of my PipelineObjects with the exception of the Default ParameterObject so I'm not sure what the error is referring to. Does anyone have any ideas as to what may be going on here? Thanks!

Turns out the Default pipelineObject needs a type of Default
