A strange case - when runningnpm run lint onthis sample repo, theno-misused-spread rule crashes with the following error:
Oops! Something went wrong! :(ESLint: 9.19.0TypeError: Cannot read properties of undefined (reading '0')Occurred while linting /Users/benj-dobs/Documents/tseslint-repro/index.tsx:6Rule: "@typescript-eslint/no-misused-spread" at Object.getWellKnownSymbolPropertyOfType (/Users/benj-dobs/Documents/tseslint-repro/node_modules/ts-api-utils/lib/index.cjs:919:72) at /Users/benj-dobs/Documents/tseslint-repro/node_modules/@typescript-eslint/eslint-plugin/dist/rules/no-misused-spread.js:156:30 at Array.some (<anonymous>) at isIterable (/Users/benj-dobs/Documents/tseslint-repro/node_modules/@typescript-eslint/eslint-plugin/dist/rules/no-misused-spread.js:156:10) at checkObjectSpread (/Users/benj-dobs/Documents/tseslint-repro/node_modules/@typescript-eslint/eslint-plugin/dist/rules/no-misused-spread.js:122:17) at ruleErrorHandler (/Users/benj-dobs/Documents/tseslint-repro/node_modules/eslint/lib/linter/linter.js:1160:48) at /Users/benj-dobs/Documents/tseslint-repro/node_modules/eslint/lib/linter/safe-emitter.js:45:58 at Array.forEach (<anonymous>) at Object.emit (/Users/benj-dobs/Documents/tseslint-repro/node_modules/eslint/lib/linter/safe-emitter.js:45:38) at NodeEventGenerator.applySelector (/Users/benj-dobs/Documents/tseslint-repro/node_modules/eslint/lib/linter/node-event-generator.js:297:26)There seems to be something about theStyleSystemObject type that causes the rule to crash. I haven't been able to reproduce this with simple types.
