Debug console flooded with WARNING: NS_ENSURE_SUCCESS(mStatus, mStatus) failed with result 0x804B000A (NS_ERROR_MALFORMED_URI): file /builds/worker/workspace/obj-build/dist/include/nsIURIMutator.h:598

The error comes from here when the IDL file is processed into a header file:

  [[nodiscard]] nsresult Finalize(nsCOMPtr<C>& aURI)
  {
    NS_ENSURE_SUCCESS(mStatus, mStatus); <<-- line 598
    nsCOMPtr<nsIURI> uri;
    mStatus = mMutator->Finalize(getter_AddRefs(uri));
    NS_ENSURE_SUCCESS(mStatus, mStatus);
    aURI = do_QueryInterface(uri, &mStatus);
    NS_ENSURE_SUCCESS(mStatus, mStatus);
    mStatus = NS_ERROR_NOT_AVAILABLE; // Second call to Finalize should fail.
    return NS_OK;
