Request for better error messages on workflow runs.

I see constant error messages (red status) on my workflow runs, even when all steps have worked successfully as I expected of them, but the status message doesn't help me know why.

In an effort to get rid of all these red status, I've stripped my workflow down to the bare minimum, and tried over and over...but still get the error in 95% of cases. I'm starting to conclude it's just Workflows being flaky for the end result status and not surfacing a useful error message:

    // Something in one of these two steps causes the workflow to show outcome of "exception" and
    // level of "error". What?
    const { foo, bar } = await step.do("test", async () => {
      const foo = "hello";
      const bar = "world";
      return {
        foo,
        bar,
      };
    });
    await step.do("test", async () => {
      return foo + bar;
    });

    // This will not cause an error...most the time...when it's the *only* step in the workflow.
    await step.do("test", async () => {
      return "foooo";
    });

    // Something in one of these two steps causes the workflow to show outcome of "exception" and
    // level of "error". What?
    const { foo, bar } = await step.do("test", async () => {
      const foo = "hello";
      const bar = "world";
      return {
        foo,
        bar,
      };
    });
    await step.do("test", async () => {
      return foo + bar;
    });

    // This will not cause an error...most the time...when it's the *only* step in the workflow.
    await step.do("test", async () => {
      return "foooo";
    });

    // Something in one of these two steps causes the workflow to show outcome of "exception" and
    // level of "error". What?
    const { foo, bar } = await step.do("test", async () => {
      const foo = "hello";
      const bar = "world";
      return {
        foo,
        bar,
      };
    });
    await step.do("test", async () => {
      return foo + bar;
    });

    // This will not cause an error...most the time...when it's the *only* step in the workflow.
    await step.do("test", async () => {
      return "foooo";
    });

    // Something in one of these two steps causes the workflow to show outcome of "exception" and
    // level of "error". What?
    const { foo, bar } = await step.do("test", async () => {
      const foo = "hello";
      const bar = "world";
      return {
        foo,
        bar,
      };
    });
    await step.do("test", async () => {
      return foo + bar;
    });

    // This will not cause an error...most the time...when it's the *only* step in the workflow.
    await step.do("test", async () => {
      return "foooo";
    });

Here is an example request ID that gives an error status for the above steps inside a workflow: IQI88BKIF6L9BMLR

Anybody else seeing this or know what's going on?

Kind of like how Trigger.dev does it (https://trigger.dev/docs/queue-concurrency).

My use case is to use browser rendering in a workflow and not allow more than 1 run at a time for this workflow in order to not go above the limitations of the browser rendering product.

You are not alone. I've posted this issue on many ocassions. Workflow can run fine, but will show errors in the runs in the dashboard. Someone the other day commented that you must JSON stringify the response from each step and then JSON Parse it back in next step, if you want to get rid of these errors. I haven't tried it yet, and none of Cloudflare examples do this, but apparently that solves these errors.

Are there any limitations for local development on workflows that might affect the accuracy of

env.WORKFLOW.get(id)

env.WORKFLOW.get(id)

?

After I invoke a long-running workflow in one codepath, a different codepath it sometimes cannot find that instance (i.e. I get

Error: instance.not_found

Error: instance.not_found

). I've been unable to find a pattern for repro, except that it seems the codepath that invokes the workflow can successfully call

get(id)

get(id)

later, even in a different instance of the worker; whereas some other codepath will always get

instance.not_found

instance.not_found

. I'm using the same binding for the same worker with the same workflow id.
