Husky & Prettier [error] Cannot read property '' of null

I have set up a husky hook for a react app, for eslint and prettier, though when I commit and the prettier script runs I get this error:

> eslint  --fix src/**/*.js


> prettier src/**/*.js --write. --config ./.prettierrc
[error] Cannot read property '' of null
> husky - pre-commit hook exited with code 1 (error)

I have checked the entire app for this '' null condition though have found nothing.

.prettierrc

    "arrowParens": "always",
    "bracketSpacing": true,
    "embeddedLanguageFormatting": "auto",
    "htmlWhitespaceSensitivity": "css",

    "useTabs": false,
    "vueIndentScriptAndStyle": false,
    "printWidth": 150,
    "tabWidth": 4,
    "rangeStart": 0
}

There is typo in format script, you can just put it as

"format": "prettier src/**/*.js --write"
