warning: matches multiple schemas when only one must validate

[carpet92]

I use VSCode to edit profiles.json settings file for Windows Terminal.

My config looks this:

// To view the default settings, hold "alt" while clicking on the "Settings" button.
// For documentation on these settings, see: https://aka.ms/terminal-documentation
// https://github.com/microsoft/terminal/blob/master/doc/cascadia/SettingsSchema.md

I noticed that VSCode shows warning in status bar:

{
	"resource": "/c:/Users/User/AppData/Local/Packages/Microsoft.WindowsTerminal_8wekyb3d8bbwe/LocalState/profiles.json",
	"owner": "_generated_diagnostic_collection_name_#0",

	"startLineNumber": 17,

}

Is there something wrong with my profiles.json? Or it's just bug?

@Zx-EvM I'm unable to find the string "Matches multiple schemas when only one must validate." in the VSCode code base, so I believe this diagnostic is coming from an extension.

Most likely this issue came from JSON Schema validator (might be earlier bundled with monaco monaco).

However other cases in the internet were caused by problems with schema and fixes there. Will try to check if Windows Terminal has problems with linked schema

[carpet92]

@RMacfarlane reopen issue maybe?

[IllusionMH]

@Zx-EvM no reason to open this issue because problem is with schema

Linked schema is "$schema": "https://aka.ms/terminal-profiles-schema".
Can be fixed by adding "type": "object" to ProfilesObject definition.

UPD. Submitted PR to fix the schema microsoft/terminal#4045
