Managing workflows with nodejs

Question

I am trying to use nodejs to manage my workflows instead of using the console. The createWorkflow method returns a 200 code but I cannot find it in the console or when listing it. Any idea what is missing? the typescript typedef has too many partials to be useful on what is needed and what is not. In the code below the list method returns correctly the workflow names I created in the console which proves that I use the parent params correctly I guess. However when I call the create method with the name of a new workflow and some code, I get this this back and a return code of 200 which should mean it was successful but can't find it. Also trying to execute it returns a not found.

return value:

Answer 1

After consulting the source for google-cloud/workflows I found where the problem was. createWorkflow is what they call a long operation and is actually 2 successive promises

const [operation] = await client.createWorkflow(request);
const [response] = await operation.promise();
