Prettier-vscode: (json-to-ast) Cannot Tokenize Symbol </> at (1:1)

[frankhale]

This issue was originally put in on VS Code but was notified that this is a Prettier issue, reference: https://github.com/Microsoft/vscode/issues/29701

I have format on save set and when I go to try to save changes to my settings.json file I get this error (in title)

Screenshots below:

[frankhale]

I can only confirm this is happening when saving settings.json (but it may be any .json file)

[CiGit]

Yes, this is due to the token at (1:1) /
Comments are not part of the JSON spec 😢
Remove the top comment (and any other comment) to fix it.

[frankhale]

Yes this definitely works but is this error something new that was added to Prettier because I've never seen it before, well since last week sometime.

[CiGit]

This is a week old. Since prettier formats JSON(real json for now) and others: https://github.com/esbenp/prettier-vscode/releases/tag/v0.20.0

[frankhale]

@CiGit thanks for clearing up my confusion!

[jitendravyas]

I'm also getting this problem. What to do?

[frankhale]

Remove anything that doesn't conform to the JSON spec, eg. comments (that's probably what is causing the issue, at least that was what was causing mine)

[thedamon]

Is there a way to turn off parsing for particular files or allow non-strict JSON parsing?

[CiGit]

For particular files, not yet.
non-strict JSON: not yet.
If you need to format pseudo JSON, IMO the best choice you have is to rely on the default formatter which does it's job.
To do so: empty jsonEnable array.

Is it still not possible to have prettier ignore formatting settings.json file?

This issue is really annoying and I can't remove the comments from settings as I use them for my personal documentation.

[krokofant]

@nikitavoloboev I believe it will be possible with the next prettier release since the fix was committed 7 days ago. No idea when it'll be out though.

"prettier.jsonEnable":[]
works for me.
