Completion does not work well in recent commits when capabilities.textDocument.completion.completionItem.snippetSupport = true (and no snippet plugins are used?) about ddc-source-lsp HOT 6 CLOSED

Hi. I have tested it and empty items.
(I don't reproduce your error)

It is from capabilities.textDocument.completion.completionItem.snippetSupport = true.
gopls returns snippet items and it is filtered.
Because you don't set snippetEngine param.

{
  label: "fmt",
  textEdit: { range: { end: [Object], start: [Object] }, newText: "fmt" },
  filterText: "fmt",
  preselect: true,
  sortText: "00000",
  kind: 9,
  detail: '"fmt"',
  documentation: { kind: "markdown", value: "" },
  insertTextFormat: 2
},

insertTextFormat: 2 means snippet.

First of all, the basic premise is that a major renovation has recently taken place; please re-read the doc.

And to solve this case1, register snippetEngine (:h ddc-source-nvim-lsp-param-snippetEngine).
gopls returns all candidates as a snippet if snippet=true. So, if the snippetEngine is not registered, they will be filtered. If you don't want to use the snippet plugin, one solution is to change capabilities.

local capabilities = require('ddc_nvim_lsp').make_client_capabilities()
capabilities.textDocument.completion.completionItem.snippetSupport = false

error messages in :messages

I think the error message is from older commit.
It is bug and it is already fixed. So the items are filtered.

I have updated FAQ.

The issue is improved. Please update.
