Output or Error

Cannot read properties of undefined (reading 'val')                                                             
Occurred while linting <FileDirectory>:11
Rule: "vue-pug-sfc/this-in-template"

Expected Output

No Error, but the eslint error for require-v-for-key

Additional Context

First of all thanks for the amazing work!. This will helps us write Pug templates :D.

In regards to the bug, I found files that had the require-v-for-key rule in effect and works correctly. Only on this file it throws the undefined error. I also checked the rules one by one (because it says the error is on this-in-template) and the rule 'require-v-for-key' was the one throwing the error.

If the key is added to the file correctly there are no errors and all works perfectly. So i think its an error of the rule. Can you check what may be causing this error?

Currently I'm hardly busy in another project, so I may have not time for a week or two
But I can review stuff 🙂 if you are happy to open a PR

I think I resolved this issue on this PR -> #144.

[Shinigami92]

Is this urgent to be released for you? Or can I wait until we have some more stuff?

[juakotorres]

It's not urgent, can wait for more changes.
