[Qy742698]

if (typeof path !== 'string') { return reject(addCode('EINVAL', new TypeError('Missing argument "path" '))); } try { ReactNativeBlobUtil.exists(path, (exist, isDir) => { resolve(isDir); }); } catch (err) { reject(addCode('EUNSPECIFIED', new Error(err))); }

ReactNativeBlobUtil.exists : Possible call error here , It should be ReactNativeBlobUtil.isDir()
