No valid fields to update.

Error message

No valid fields to update.

What it means

Validation error from ModelRouter.update relayed by PUT /model-routers/:id: none of the submitted fields were recognized/updatable properties, so there is nothing to change and the update is rejected rather than performing a no-op.
