SyntaxError: Unexpected end of JSON input

I got this exception when I receive/send image files just now.

SyntaxError: Unexpected end of JSON input
    at JSON.parse (<anonymous>)
    at Request._callback (/home/zixia/chatie/wechaty/src/puppet-web/puppet-web.ts:565:28)
    at Request.self.callback (/home/zixia/chatie/wechaty/node_modules/request/request.js:186:22)

I believe it is a random error because I had sent/received many image files before saw this error message.

Can you look at the body content?

Will post the body content to here if I could reproduce it again.
