Code has the wrong length error message

[odinblister]

I'm trying to get this to work. I followed the instructions, and added a Print folder to my Remarkable home. The printer showed up in my list of printers. When I print, nothing happens. I then went to the cups web interface and saw that the printer "reMarkable" has the status:

"Idle - "2019/10/07 17:19:46 auth.go:62: Code has the wrong length, it should be 8""

Any ideas of what this means?

This is an error message from rmapi, you can head over to them and ask. Please report back, when you do.

I just ran into this too!

Did you authenticate with the remarkable cloud beforehand? You need to authenticate with the user that runs the backend, or you need to copy the secrets file over to the user that runs the backend.

@ofosos ahh, i didn't realize it didn't run as me! that's almost certainly the issue. i'll dig in, cheers!

[isovector]

That did it, thanks. The solution was:

# mkdir /home/cups
# vim /etc/passwd
-- change home directory for cups to /home/cups
# sudo -u cups rmapi
-- authenticate rmapi as normal

Great!

Hi, I'm having this same problem.
I've followed the instructions for installation, and on the first try of:

docker run -v $HOME/.rmapi/:/home/user/.rmapi/ -it rmapi

I get access to the shell, but when subsequently trying to run:

docker run -v $HOME/.rmapi/:/home/user/.rmapi/ rmapi help

or anything else (dropping the "help"), I get the Code has the wrong length error.

It looks to me like the token isn't being saved correctly, but I'm not sure how to fix this (or what the token should look like).

Docker version 19.03.8, build afacb8b
Linux Kernel: 5.7.14-200.fc32.x86_64

Hey @muhark this looks like an rmapi bug

[raffraffraff]

Getting the same error in my /var/log/cups/error_log. I don't have a user 'cups', and I can see that the print job runs the remarkable/rmapi command as root. So I authenticated rmapi as root. However, the CUPS error_log still shows this error.

More importantly: this log spams the /var/log/cups/error_log with over 7000 errors per second, continuously. I knew something was 'wrong' when my laptop fans kicked in. I checked the file and it was already 250mb in size. Not sure where this 'pathalogical' logging comes from but I thought I'd warn anyone else who stumbled here through a Google search.

@raffraffraff What distribution are you on that print jobs get run as root?

I just ran into this again. The issue was that the $cupsuser was my account, but whoami running the script was cups. Thus, the cups user was trying to use my credentials, but it didn't have permission to read them. I changed the RMAPI_CONFIG line to point to the cups credentials:

export RMAPI_CONFIG=/home/cups/.config/rmapi/rmapi.conf

and everything worked fine.
