I’m trying to deploy a release, but I’m getting an immediate failure just after the `update-fetch [Download_Enter] -> update-status-report [none]` transition. The error reported is 400 `error uploading logs: (request_id: ): uploading logs failed, bad status 400 server error message: no messages: invalid deployment log"`

The same deployment also gets installed on other machine types, and these are fine.

Any clue on how I could workaround that problem ?

I’ve observed a similar/the same issue:

I just ran into the same problem. This error appeared for me after testing a restrictive firewall rule, which prevented the device from connecting to the internet after an OTA update. I assume that, as a result, Mender was unable to record the update process as either successful or failed. I then powered off the device and booted it normally from the old boot slot. When I attempted to trigger another update, this error occurred.
