Correct Value not accepted in required attribute

[CLaborieSLB]

Describe the bug
Getting error "Value is not accepted. Valid values: true" for the required attribute in my path parameter description... while the value I have in my YAML file is actually true.

To Reproduce
/pets/{pet-key}:
get:
tags:
- 'Animals'
summary: 'Returns a single Pet based on its Key'
description: 'Returns a single Pet based on its unique Pet Key'
operationId: getPetByKey
parameters:
- name: pet-key
in: path
required: true
schema:
type: string
description: 'The Pet Key'

Expected behavior
Value is true (ie. correct and expected) so no error should be raised.

Screenshots

Environment:

• Extension version: 1.1.4
• VS Code version: 1.100.2
• Operating System: Windows 11 Enterprise

Additional context
Started appearing recently on all my APIs... while I did not have the issue earlier

I am seeing the same thing. Very frustrating. Any updates on the cause?

Seeing the same as well. Has this changed recently?

Hi, I figured out what is causing the problem for me. Not sure if it's the same for anyone else but wanted to report back here. On my computer, I disabled the 42Crunch OpenAPI (Swagger) Editor extension and restarted extensions, then the Spectral linting errors are correct (and match what you get when using the spectral CLI).
I may report this issue there as well in case someone can find a root cause for the false error reporting.

Looks like there's a known issue with one of the YAML library dependencies, see 42Crunch/vscode-openapi#329.

@annegentle Thank you very much for the suggestion!
I was not using the 42Crunch OpenAPI (Swagger) Editor extension...
However I was using Arjun G's Swagger Viewer
And the same solution worked for me... after disabling this extension, the issue is gone!
