Bug: Validation Error with @stoplight/spectral-rulesets 1.19.0

[tomo-kn]

Describe the bug
After upgrading to @stoplight/spectral-rulesets version 1.19.0, we encountered a validation error that was not present in version 1.18.1.

The error message indicates a problem with spectral, specifically a TypeError: Cannot read properties of null (reading 'type').

[ERROR] There was a problem with spectral.
[ERROR] Cannot read properties of null (reading 'type')
[ERROR] Additional error details:

To Reproduce

1. Upgrade to @stoplight/spectral-rulesets version 1.19.0.
2. Run the OpenAPI validation using ibm-openapi-validator or spectral.
3. Observe the validation error

Expected behavior
The OpenAPI validation should pass without any errors, as it did with @stoplight/spectral-rulesets version 1.18.1.

We encountered the same error. By adding the following configuration to .spectral.yaml to disable the array-items rule, the error was muted.

rules:
  array-items: off

It appears that array-items was added in @stoplight/spectral-rulesets 1.19.0 . There may be a bug in this rule 🤔

  • feat(rulesets): add new rule that requires sibling items field for type array #2632
