There are no profiles (that would make sense - new concept?)
Going into application/devices/ some_device/configuration, it show a device profile name from v3 system but clicking on it yields the above error.
Hopefully I can just add some device profiles, swap the profile assigned to each device and be good to go. I have other v4 systems working fine, this is the first time I have used the v3 to v4 tool.
I just ran into this exact issue. would you mind sharing more about your environment? are you using any kind of proxy? What version of redis are you using? In my case, i’m using an nginx proxy and redis 7. I’m curious to know if we have any similar that might lead us to a solution.
I found the issue in the “mode” column of the device table inside the network server database on the v3 side. https://github.com/chirpstack/chirpstack-v3-to-v4/blob/master/main.go#L1146 looks be placing an “A” in that field if its blank, but I’m not sure thats working. I added this detail to the github repo issue as well.
