"Parse error on line 1: Expecting 'STRING'..." - How do I find out what extension is causing this issue?

macintacos commented 4 years ago

Issue Type: Bug

I have a very reliable issue when it comes to opening new, untitled files that start out as plaintext (a very common usage pattern for me). I start typing, and everything is fine, but then when I delete that line of text, I get the following error which does not go away until I reload the window:

Parse error on line 1:

^
Expecting 'STRING', 'NUMBER', 'NULL', 'TRUE', 'FALSE', '{', '[', got '1'

Here's a gif demonstrating the issue.

My question is not how do I fix this, because I've already searched other issues that have been opened here (e.g. #67046, #56193) and see that it's probably an extension and I have to go hunt it down. The problem is that I have a lot of (probably too many) extensions, and I can imagine that this will get tedious trying to hunt it down.

VSCode doesn't really provide anything useful about what extension generated the error that I'm seeing. When I right click and copy the message, I'm given this information, which I don't find to be particularly helpful:

{
    "resource": "Untitled-1",
    "owner": "languageErrors31",
    "severity": 8,
    "message": "Parse error on line 1:\n\n^\nExpecting 'STRING', 'NUMBER', 'NULL', 'TRUE', 'FALSE', '{', '[', got '1'",
    "startLineNumber": 1,
    "startColumn": 1,
    "endLineNumber": 1,
    "endColumn": 1
}

Is owner supposed to have meaningful significance to help me debug this? I've searched around and this doesn't really give me much to go by.

Can I get some pointers on how to tackle this properly so that I don't waste an hour trying to figure it out (teach a man to fish and all that)? If the only solution really is "disable extensions one by one", can we use this issue as a catalyst to make this better/easier to debug? I couldn't find any issues that are trying to tackle this problem specifically, but please let me know if this is a duplicate and I'll go chime in there.

Generally extension creating these diagnostics shall add the source of the diagnostic which is missing in this case. I do not think we have extension information available in our diagnostics model and I see this is useful in the case.

@jrieken Is it possible to add extension id as source if missing?
