attaching to serial console is not working

[RaitoBezarius]

Whenever I try to do scw attach or scw run --attach, it attaches to nothing, i.e. "You are connected", wait some seconds and return the shell.
I'm trying to make work https://github.com/moul/scaleway-ipxe to have NixOS install through iPXE, but I have this error:

spawn slow-stream --raw -b 1 -i 10 --stdout-passthrough -- scw run --attach --commercial-type=VC1S 50G
You are connected, type 'Ctrl+q' to quit.
panic: provided file is not a console

I'm not sure how to diagnose this.

Hello @RaitoBezarius ! After some digging it looks like it's because of changes in some vendors. Version 1.19 still works so I encourage you to use this version intead of the 1.20 if you want to make it work. Tough it's an issue on moul/gotty-client not on the cli itself. I'll try to fix it if I find some time though!

@RaitoBezarius need moul/gotty-client#77 merged then we'll bump the dep on the cli :)

Thank you a lot for your fast response (& fix), @Sh4d1 I really appreciate it :)
I'll wait for your PR to be merged upstream
