What did you do?

I am using vim withthe latest version of YouCompleteMe which I believe uses gopls under the hood. I would like to verify the following using the gopls cli but have not been able to figure out how to get autocomplete suggestions with the cli. Direction there would be appreciated as it would likely help narrow down if this is actually a gopls issue or a you complete me issue.
When autocompleting on empty struct literals

When populating an autocomplete list inside an empty struct I get the same autocomplete recommendations as outside the struct (all available identifiers):

What did you expect to see?

The list restricted to only the fields of the struct: Asdf, and Qwer in the above case

More info

When the struct literal has any token in it, even if that token is not a valid member, I do see the autocomplete suggestions as desired

[muirdm]

This is what I see in Emacs:

I recommend you look at an RPC trace to see the back and forth between gopls and your editor. You can enable this on the gopls side (https://github.com/golang/tools/blob/master/gopls/doc/troubleshooting.md#capture-logs) or perhaps your lsp client can also dump out the details.

If you suspect your editor/client may be to blame, you can try VSCode to see how it behaves.

[suzmue]

The gopls cli does not currently support autocompletion, but as @muirdm suggested, you could try using a different editor or client that also uses gopls (for other vim clients you can check this list: https://github.com/golang/tools/blob/master/gopls/doc/vim.md).
