Problems with nested snippet insertion

[tnrich]

I couldn't leave a comment on any of the many issues that seemingly address this error:

#26907

#27015

#26915

#27015

because they were all locked. I am still definitely hitting this error and am on the latest possible stable vscode version:

Here is a screenshot of the issue popping up:

I'm not sure what causes the error to start occurring, but once it starts, every time I try to tab complete anything I get this annoying message and the cursor position gets off in a funky way such that I can't use my regular snippets.

Can you open the console (Help -> Toggle Developer Tools -> Console) and share any error messages there with call stacks?

[tnrich]

I will once I'm able to reproduce it. I restarted so it might be a little bit before the error starts up again.

I'm getting this error with a custom code snippet (elm.json, for elm language in this case):

"Function definition w/ 2 arguments": {
	"prefix": "fn2",
	"body": [
		"$1 : $2 -> $3 -> $4",
		"$1 $5 $6 =",
		"    $0"
	],
	"description": "Function definition w/ 2 arguments"
},

while this is working:

"Function definition w/ 1 arguments": {
	"prefix": "fn1",
	"body": [
		"$1 : $2 -> $3",
		"$1 $4 =",
		"    $0"
	],
	"description": "Function definition w/ 1 arguments"
},

The developer tools:

After restarting vscode it's working as expected.

Exciting... I have been getting this via error telemetry since a long time but was never able to reproduce.

Not exciting... @Braincompiler I jump on your snippet but it seems that you are taking this issue hostage as it unrelated to the invalid argument issue mentioned before. Still, please try to prodive reproducible steps. Just inserting the snippet doesn't do it, sadly...

@tnrich I am sorry but we do need steps for this... Also, don't believe that all illegal-argument errors have the same cause. It's a general we use and it can occur in different places and be triggered in different ways
