TypeError: Cannot read property 'name' of undefined at require-default-props.js:291:23 #1029
Description
Overview
Seen another instance of the Cannot read property 'name' issue which has already been raised in issue #1021. Again using the following package versions:
- eslint-config-airbnb@14.0.0
- eslint-plugin-react@6.9.0
Error returned is:
Cannot read property 'name' of undefined TypeError: Cannot read property 'name' of undefined at isPropTypeAnnotation (/Users/user/path/org/project/node_modules/eslint-plugin-react/lib/rules/require-default-props.js:291:23) at Object.ClassProperty (/Users/user/path/org/project/node_modules/eslint-plugin-react/lib/rules/require-default-props.js:461:13)After checking require-default-props.js its failing at this point:
function isPropTypeAnnotation(node) { return (node.key.name === 'props' && !!node.typeAnnotation); }After inspecting the node I have the following returned:
Node { type: 'ClassProperty', start: 301, end: 414, loc: SourceLocation { start: Position { line: 11, column: 2 }, end: Position { line: 15, column: 3 } }, computed: false, variance: null, static: true, value: Node { type: 'ObjectExpression', start: 320, end: 414, loc: SourceLocation { start: [Object], end: [Object] }, properties: [ [Object], [Object], [Object] ], range: [ 320, 414 ], _babelType: 'ObjectExpression' }, range: [ 301, 414 ], _babelType: 'ClassProperty', parent: Node { type: 'ClassBody', start: 296, end: 1235, loc: SourceLocation { start: [Object], end: [Object] }, body: [ [Circular], [Object], [Object], [Object] ], range: [ 296, 1235 ], _babelType: 'ClassBody', parent: Node { type: 'ClassDeclaration', start: 265, end: 1235, loc: [Object], id: [Object], superClass: [Object], body: [Circular], decorators: [Object], range: [Object], _babelType: 'ClassDeclaration', parent: [Object] } } }After inspecting then source in question returned from context.getFilename() and checking the line number, I have the following code:
export default class Anchor extends Component { static propTypes = { active: PropTypes.bool, underline: PropTypes.bool, tooltip: PropTypes.array, } ... }After checking the source comments here this all appears to be valid.
As you can see in the above node output there is no key property? Has there been a breaking change here? Any insight would be greatly appreciated.
