The error that you are receiving is pretty clear. Some parameters (project, subnetwork, service_account, TransformFunctionName) are not recognised and javascriptTextTransformFunctionName is missing.

Check again the documentation examples on how to launch jobs with the DataflowTemplateOperator as well as the docs for the operator itself.

In a few words, TransformFunctionName should be renamed to javascriptTextTransformFunctionName and project, subnetwork and service_account should be removed from the parameters dict and specified in dataflow_default_options dict instead.
