"There are task errors" while typing in tasks.json

[roblourens]

• Have a task like this:

{
	"type": "npm",
	"script": "web",
	"label": "Run web",
	"isBackground": true,
	"presentation": {
		"reveal": "never"
	}
}

• Add this

"problemMatcher": {
	"background": {

	}
},

• Get a warning popup immediately, "There are task errors. See the output for details"
• I'm still typing, I know there are errors, it should leave me alone for a minute or until I close the editor

It's good to know that my task isn't correct but can it just be shown as an underline in the editor?

I'll add a debounce delay to config changes.

[alexr00]

I added a 1 second debounce to try to balance getting early feedback on your task being incorrect and getting the notification immediately

I've encountered this too.

couldn't we update without the delay but if something is not correct, wait 20 seconds, check again, then decide whether or not to show the error notification?

We should align with how language servers/lint extensions normally work imo
