Describe the bug

After Release v0.45.1, every time I save a non .go file in my project (for example, a .json or Makefile) I receive the error Command 'gopls.package_symbols' failed: Error: no package metadata for file {filename}

Steps to reproduce the behavior:

1. Save any non .go file (for example a .json) inside a Go project.

Screenshots or recordings

Command 'gopls.package_symbols' failed: Error: no package metadata for file file:///{filepath}/{filename}.json.

I had the same problem.
Solved it by switching "Go for Visual Studio Code" extension from pre-release version to release (v0.44.0).
I don't know if you want to stay on the pre-release version, but I had to get rid of those error messages somehow.

Yeah I had to leave the pre-release due this error.

Thanks for reporting this. The go extension should not trigger any package_symbol command against non-go file.

This is a mistake. Let me fix it and release v0.45.2 to make the pre-release version healthy.

It also needs to filter out non-file schemes, since those are also rejected (I have gotten the error for the git scheme, untitled, etc).

[h9jiang]

Hi jakebailey,

Thanks for the reminder. You are correct, I will also add a condition for checking doc.uri.scheme !== 'file', gopls package symbol does not work for scheme other than 'file'.

I was able to re-produce this with untitled scheme (when it's empty, its considered as plain text, but later considered as languageID go resulting in failure.)

[gopherbot]

Change https://go.dev/cl/649258 mentions this issue: extension/src: reload package symbol for only go file and file scheme

[h9jiang]

The fix is released in vscode-go insider version v0.45.2. Also a change in gopls.package_symbols released in gopls v0.18.0-pre.5.
