  import { BaseSource, DdcGatherItems } from "https://deno.land/x/ddc_vim@v3.7.0/types.ts";
  import { GatherArguments } from "https://deno.land/x/ddc_vim@v3.7.0/base/source.ts";

type Params = Record<string, never>;

type UserData = { data: string; };

export class Source extends BaseSource { gather( _args: GatherArguments, ): Promise<DdcGatherItems> { return Promise.resolve({ items: [ { word: "test1", kind: "A", }, { word: "test1", kind: "B", }, ], isIncomplete: false, }); }

params(): Params { return {}; } }

## How to reproduce the problem from neovim/Vim startup (Required!)

1. Insert text `te`
2. Two candidates `test1` come up
3. You try to select one, the popup closes.

FYI:
This issue is related ddc.vim.
After disabling ddc.vim with call `ddc#disable()`, you can confirm that `<C-n>/<C-p>` works correctly by directly hitting `pum#open()` with `<C-x>`.

Fixed.

Please update pum.vim.
