Collecting LSP log

Each language server has a setting <ID>.trace.server. With it, you can see the exact messages exchanged in the LSP protocol.

This info can help the maintainer debug your issue.

Here's how to collect it:

1. Set "vetur.trace.server": "verbose".

2. Open Panel -> Output -> Vue Language Server. You should already see a lot of messages like this:

   [Trace - 12:13:53 PM] Received notification 'textDocument/publishDiagnostics'.
   Params: {
       "uri": "file:///Users/pine/Code/mine/vetur/veturpack/src/Test.vue",
       "diagnostics": []
   }
   

3. Click the Clear Output icon (next to the Output Channel picker and the lock icon).

4. Perform the minimal action to reproduce your issue. For example, trigger a completion.

5. Attach the complete log of Vue Language Server channel to the issue.
