Create a workflow using Durable Functions in Sandbox does work

Question

After reviewing previous questions to the same issue and attempting to duplicate recommendations this particular exercise does not work. It would be nice if someone would update the exercise with the appropriate steps or assure the sandbox is correct.

Thanks for posting your question in the Microsoft Q&A forum.

Make sure your HttpStart function looks something like this:

const df = require('durable-functions');

module.exports = async function (context, req) {
    const client = df.getClient(context);
    // Rest of your function code
};

Ensure your package.json includes the latest version of durable-functions , and if possible, try setting up a local development environment for Azure Functions to test your code outside the sandbox.
