E900: Invalid channel id (again?) about vim-go

[sbinet]

hum... compiling the same gopls version but with golang/go@c19c4c566c (ie: Go1.21.0) works.

and it would seem that the "invalid channel id" error comes up when compiling gopls with golang/go@5fa4aac

can people reproduce it ?

[bhcleek]

The most common reason for the Invalid channel id error is because gopls has crashed. Given that you can duplicate this with a specific revision of the Go source code, I recommend that you file an issue in github.com/golang/go about it.

Would you have a set of shell commands that'd replicate the set of vim operations I've sketched above ?

Ie : what does vim-go send to gopls ?

[bhcleek]

You can add let g:go_debug=['lsp'] to see the logs of requests and responses to gopls from vim-go. That may be enough for the gopls team to understand what's going on. Alternatively, they may ask you to use the -logfile option. You can use g:go_gopls_options (see :help g:go_gopls_options) to set it.

However, the very simple reproduction case you've described may be all they need.
