Cannot read properties of null reading "write" about coc-discord-rpc

[Paxxous]

I have the same issue. As well as:
[coc.nvim] RPC: TypeError: e.forEach is not a function

[ken-soares]

can't get this to work either

[Nuddel69]

I'm having the same issue. Did you ever figure it out?

[leonardssh]

This error occurs when the rpc doesn't find the discord client (it is not started or rpc doesn't have permissions).

I've been getting this issue lately - but it only seems to happen when I use my window manager (Awesome) instead of my usual desktop environment (KDE). So it's probably not an issue with the plugin (for me), but does anyone know what might cause this in my situation?

[AucaCoyan]

I'm getting the same error. Is there any configuration I need to setup to make it work?

[knaeve]

@leonardssh Uhm, facing the same bizzare issue? Would you mind helping us?

[knaeve]

Seems like all issues are dead.

[TudbuT]

@leonardssh this issue is 3/4 of a year old and fatal.

[leonardssh]

@TudbuT I know about this issue, I tried to solve it, but to no avail. At the moment I don't have the time and environment to start try solving it again.

[knaeve]

Uh, this sucks! :(

[xhayper]
