Hi,
After reading open-balena-api v0.76.3 sql migrations and Device can't register with API, it seems like the supervisor after balenaOS 2.49.0 isn’t compatible with the latest release of openBalena, see this issue. So the problem is noted, but there isn’t a fix (yet) unfortunately. I’m waiting for the fix myself, so let’s hope they’ll release a new (stable) version soon
