Release notes

miniflare@4.20260721.0

Minor Changes

• #14742 34430b3 Thanks @​pombosilva! - Add support for redacting sensitive Workflows step output in local dev.

  Steps configured with sensitive: "output" now have their output redacted to [REDACTED] in step logs and step-output responses when running Workflows locally, matching production behavior. The real value is still passed to downstream steps, and step errors are never redacted.

Patch Changes

• #14715 42af66d Thanks @​dependabot! - Update dependencies of "miniflare", "wrangler"

  The following dependency versions have been updated:

  Dependency	From	To
  @​cloudflare/workers-types	^5.20260714.1	^5.20260721.1
  workerd	1.20260714.1	1.20260721.1

• #14766 4815711 Thanks @​gianghungtien! - Report the Worker's error for HEAD requests instead of an internal JSON parse error

  A Worker that threw on a HEAD request (for example curl -I) logged SyntaxError: Unexpected end of JSON input from miniflare's internals rather than the actual error, and dispatchFetch() rejected with that same misleading error. workerd drops response bodies for HEAD requests, so the serialised error never reached the code that revives it.

  The error is now also carried in a header, which survives HEAD, so the original message and source-mapped stack are reported for every method. When no payload is available the reporting degrades to a plain error rather than surfacing a parse failure.

Minor Changes

• #14562 9f04a7e Thanks @​martijnwalraven! - Add a handleUncaughtError shared option that receives uncaught Worker exceptions

  The runtime catches handler exceptions to build the 500 response, so they never reach the inspector — the one place an uncaught exception exists as a structured value in Node is the pretty-error path, where the error report from the Worker is revived into a source-mapped Error. Embedders can now pass handleUncaughtError: (error: Error) => void to observe that revived error programmatically; logging behavior is unchanged.

  The hook fires only where the pretty-error path does: requests reaching the Worker through the entry socket (a browser or another HTTP client against the dev server). dispatchFetch() is unaffected — it always sets MF-Disable-Pretty-Error, and the entry worker then propagates the exception by rejecting the returned promise instead, so dispatchFetch() callers already receive the error directly and the hook is not invoked.

• #14706 cb6c3f9 Thanks @​edmundhung! - Add Durable Object storage access to createTestHarness()

  You can now execute SQL against a SQLite-backed Durable Object to seed or assert the storage state.

  const server = createTestHarness({
    workers: [{ configPath: "./wrangler.json" }],
  });
  await server.listen();
  const worker = server.getWorker();
  const storage = await worker.getDurableObjectStorage("COUNTER", {
  name: "user-123",
  });
  await worker.fetch("/counter/user-123");
