Will fix this! In the meantime:

{
  // CallInputs section (MODEL_ID, etc)
  startRequestId: "ANYTHING"
}

It used to be (optional) but due to a different feature that obviously broke this.

Oh actually, this wasn't broken, the particular user above was calling with the wrong inputs (no callInputs key).
