Reproduction Example/SDK Setup

No response

Steps to Reproduce

Create failing code

await step.do('will fail', async => {
  fail();
};

Expected Result

One error report is generated once all step.do retries have been exhausted, or on a NonRetryableError

Actual Result

One error is generated on each retry, thus creating a LOT of duplicate errors (see screenshot; where 6 errors have been created for the same issue)
