Error during NUI

Hello, here I noticed that when I typed a command I had an error in the console, can you tell me what it is?

"Error during NUI callback chatresult: citizen / scripting / lua / sheduler.lua: 243 bad argument # 1 to ‘unpack’ (table expected, got nil)

Thank you for your help.

Hi same here… any call to an NUI Callback throws this…
mostly by passing an empty JSON object to the JSON.Stringify function.

What’s wrong ?

Possible to prevent this error from generating?
Sorry I use a translator.

Thank you
