1. A sample program that reproduces the issue, if possible.
1. The output of `gopls version` on the command line.
1. The output of `gopls -rpc.trace -v check /path/to/file.go`.
1. gopls logs from when the issue occurred, as well as a timestamp for when the issue began to occur. See the [instructions](#capturing-gopls-logs) for information on how to capture gopls logs.
For VSCode users, the gopls log can be found by navigating to `View` -> `Output` (or `Ctrl+K Ctrl+H`). There will be a drop-down menu titled `Tasks` in the top-right corner. Select the `gopls (server)` item, which will contain the `gopls` logs.
To increase the level of detail in your logs, add the following to your VS Code settings:
```json5
"go.languageServerFlags": [
"-rpc.trace"
]
```
To start a debug server that will allow you to see profiles and memory usage, add the following to your VS Code settings:
```json5
"go.languageServerFlags": [
"serve",
"-rpc.trace",
"--debug=localhost:6060",
],
```
You will then be able to view debug information by navigating to `localhost:6060`.
#### Other editors
For other editors, you may have to directly pass a `-logfile` flag to gopls.
To increase the level of detail in your logs, start `gopls` with the `-rpc.trace` flag. To start a debug server that will allow you to see profiles and memory usage, start `gopls` with `serve --debug=localhost:6060`. You will then be able to view debug information by navigating to `localhost:6060`.
Once you have filed an issue, you can then try to restart your `gopls` instance by restarting your editor. In many cases, this will correct the problem. In VSCode, the easiest way to restart the language server is by opening the command palette (Ctrl + Shift + P) and selecting `"Go: Restart Language Server"`. You can also reload the VSCode instance by selecting `"Developer: Reload Window"`.
