Fix srcToken error

[mdbraber]

Fixes #1402 @pjkaufman could you review?

[pjkaufman]

Hey @mdbraber , thanks for creating a potential fix for the issue. My concern right now is how it got as far as it did in the logic since #1402 implies that the logic actually ran for yaml key sort. The logic should not make it past this check:

obsidian-linter/src/rules/yaml-key-sort.ts

Lines 41 to 44 in cce4f98

	const oldYaml = getYAMLText(text);
	if (oldYaml === null) {
	return text;
	}

If there is no YAML, then it should just skip the rule as a whole. So I am more worried that this is a bandaid that hides the reason that getYAMLText is returning a non-null value for a file without YAML.

Should this not be before line 64 since that is where the error is happening since that allows us to exit immediately after we know there is no content in the YAML? At least, that is where the error happens for me locally.

Yes - you're right. Or should the code of

obsidian-linter/src/utils/yaml.ts

Line 31 in 1877e2b

if (!yaml) {

be changed to check for an empty match by changing it to if (!yaml || yaml[1] == "")

Returning an empty YAML string is fine from my understanding since it is possible to have YAML that is just empty and I would expect the content to be an empty string in that case. I am not sure if things would break if we also returned null for empty strings for the YAML.

I think that the proposed solution just before getting an empty document makes the most sense to me at this time.

It has been a little a while on this. I am going to just go ahead and merge this since it looks to fix the issue.

Thanks Peter!
