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 going to `"View: Debug Console" -> "Output" -> "Tasks" -> "gopls"`. 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`.
If you are unsure of how to pass a flag to `gopls` through your editor, please see the [documentation for your editor](user.md#editors).
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"`.
