What can be used to return Neo4J data from a promise in a dialog context or waterfallStepContext step within the Microsoft Bot Framework Nodejs

Question

In this waterfall step,

public async processRequest(stepContext: WaterfallStepContext): Promise<DialogTurnResult> { ...

I am trying to return or end the dialog with the following,

return await stepContext.endDialog(JSON.stringify(dataPayload));

However I can't return the step inside of the session.run(query) result.

Is there a way to use the Waterfall step to have a response function to return the stepContext?

Here is the sample Neo4j driver session,

session
  .run(query)
  .subscribe({
   onNext: function (record) {
   console.log(record);
   // return await stepContext.endDialog(JSON.stringify('dataPayload')); <-- not intiating
  },
  onCompleted: function () {
  session.close();
  },
  onError: function (error) {
  console.log(error);
  }
  });

If I understand the question correctly it appears that you would like to wait for the query to complete, buffering all results before proceeding in the waterfall step?

In that case use the promise api:

const result = await session.run(query);
session.close(); 
await stepContext.endDialog(JSON.stringify(dataPayload));
