GoImports no longer shows auto suggested packages

[nwnt]

Hi there, I'm trying to use GoImports to auto suggest a package I need to import. When typing in the partial name of the package and hitting tab, I didn't get anything:

It looks like the plugin tried to list the packages, but nothing shows up.

And sometimes I would get a warning go doc failed.

I use the default configuration of go.nvim with the default lazyvim. no other configurations were applied. Do you know what has gone wrong here?
