Handle unresolved accessibility action entries

[marcshilling]

What changed

Skip undefined entries returned by jsx-ast-utils while inspecting an accessibilityActions array.

Why

When an array contains conditional spreads that cannot be resolved statically, getPropValue can return undefined for those entries. The rule currently assumes every evaluated entry is an object and reads action.name, which throws a TypeError and terminates the entire ESLint run.

Skipping only unresolved entries lets ESLint continue while preserving the existing diagnostics for other invalid values.

My code that was crashing this

accessibilityActions={[
  ...(index > 0 ? [{ name: 'decrement' }] : []),
  ...(index < items.length - 1 ? [{ name: 'increment' }] : []),
]}

Verification

• yarn lint
• yarn flow
• yarn test:ci (212 tests)
• yarn build
• Manually ran the built rule against a conditional-spread reproduction
