sorry, I missed the issue opend.

Could you show me your .org file? (to reproduce your error) It's better with minimal config of your environment.

[stardiviner]

I got the same error. I'm using the latest version Org Mode which is loaded from master branch source code. the latest commit is 96cc762ff master upstream/master Remove duplicate selection letters from tag filter prompt.

[lurdan]

hmm...I can't reproduce it. It runs successfully with its sample conversions (README.org).

• emacs26 (26.2~1.gitfd1b34b-kk1+18.04)
• org-mode (master 73c0989037e6bf9ed39e57867a662b861e9d0af8)
• node (v11.12.0)

[stardiviner]

I'm using Emacs version GNU Emacs 26.2 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.8) of 2019-04-13. And with minimal config, still have this error.

[lurdan]

Would you put these somewhere?

• your minimal config which reproduces the problem
• your target code block which raises error

And here is my typescript code block:

#+begin_src typescript :tangle "data/code/wechaty-demo.ts"
import { Wechaty } from 'wechaty'

Wechaty.instance()
.on('scan',        qrcode  => console.log('扫码登录：' + qrcode))
.on('login',       user    => console.log('登录成功：' + user))
.on('message',     message => console.log('收到消息：' + message))
.on('friendship',  friendship => console.log('收到好友请求：' + friendship))
.on('room-invite', invitation => console.log('收到入群邀请：' + invitation))
.start()
#+end_src

Weird, when I test again, this error gone.

hi, thanks for your snippet.

I've found that ":results output" setting seems to cause the error, because I didn't care about org-babel parameters. I will take care of it later, or @dop's commit 7782749dc54a6b76cc4e3988247685e1a02bfe42 will fix the problem.
