Vim-go: Vim error in hoverHandler when open go file with active module support

Created on 7 Aug 2019 · 4Comments · Source: fatih/vim-go

When I open a go file with activated modules I get the following error in VIM.

2019-08-07_1151x364

Whenever I change to another line in the code I get the error again

The error comes from vim-go and points to here: https://github.com/fatih/vim-go/blob/master/autoload/go/lsp.vim#L594

Why do I get the error and how can I fix the problem? Thanks!

Configuration (MUST fill this out):

vim-go version:

1.20

Vim version (first three lines from `:version`):

8.1.1635

Go version (`go version`):

1.12.5

I'm still seeing this with latest vim-go and gopls. When I enable let g:go_auto_type_info = 1 and hover the cursor on import statements, such errors show up.

import (
    "net/http"
)

gopls and vim-go have each changed quite a bit since vim-go v1.20. vim-go's master is pretty stable right now; I recommend upgrading to vim-go's master, running :GoUpdateBinaries gopls, restart vim afterwards and see if you still have problems.

I just updated yesterday all of my Vim-Plugins and also executed :GoInstallBinaries. But today I tried your tip with :GoUpdateBinaries gopls and it helped! Thank you very much!

I just started running into this too, after recently updating gopls.

To be fair, the gopls utility is rapidly changing, so it might just be a new error condition for it.
