SpiffWorkflow.bpmn.parser.ValidationException.ValidationException: No DMN Diagram available with id "None", Available DMN ids are: product_prices. about spiffworkflow

Running ./spiff-bpmn-runner.py -p order_product -b bpmn/tutorial/task_types.bpmn -d bpmn/tutorial/product_prices.dmn (note error in the path of your provided command) works fine for me.

It looks like you've created your own runner based on spiff-bpmn-runner.py which passes in a parser that expects spiffworkflow extensions on task specs, which are in fact different from camunda extensions. If you want to use our (limited) support for camunda, see camunda-bpmn-runner.py for an example of how to create a parser that knows about those extensions.

Also, if you continue to have trouble, please open issues relating to the example code in https://github.com/sartography/spiff-example-cli
