requested to merge 1629580/code:issue-22-24-key-error-missing-json-record into issue-22-24-key-error-missing-json-record
When the retries for the OTA timeout are exhausted, the record function will now raise an Error. The restore function now checks if a file exists before opening it. Furthermore, the restore function now catches KeyError and propagates a Warning, then it continues with the next device.
