ESLint Error: Cannot read property 'kind' of null

[kevanstannard]

I'm currently using airbnb lint rules plus flow typing with the following configuration:

package.json

"babel-eslint": "^7.2.3",
"eslint": "^3.19.0",
"eslint-config-airbnb": "^15.0.1",
"eslint-plugin-flowtype": "^2.33.0",
"eslint-plugin-import": "^2.2.0",
"eslint-plugin-jsx-a11y": "^5.0.3",
"eslint-plugin-react": "^7.0.1"

.eslintrc

---
  extends:
    - airbnb
    - plugin:flowtype/recommended
  plugins:
    - flowtype
  parser: babel-eslint

And just one file in the project:

types.js

type Person = {
  name: string
}

export type {
  Person
};

When running eslint on this file it generates the following error:

Cannot read property 'kind' of null
TypeError: Cannot read property 'kind' of null
    at checkDeclaration (/Users/Kevan/dev/lint-bug/node_modules/eslint-plugin-import/lib/rules/no-mutable-exports.js:10:24)

If I change the types.js file as follows, then the error goes away:

export type Person = {
  name: string
}

I'm not sure if this is best solved within this project or within airbnb but just raising it here first as the error is occurring within the import plugin code.

Thanks

Hi. It looks like this issue is already resolved in the master branch, but not yet released.

I am not really involved in the project a lot, but from some investigation: here is the commit that fixed the issue: bfdc2bb#diff-661a67441954052a3bb363a7c1398797R18

Other related issues: #660 + #758

According to this comment, a release should be coming soon: #758 (comment)
