Need help with chat commands

Hi, so as in title i have a little problem with chat commands. When i type a message with spaces, these spaces turn into commas like:
obraz

Any ideas what can be wrong?
RegisterCommand’s are client-side and i don’t affect rawCommand

Try adding " around your space-including argument.

Example:
Bad: /message I play FiveM 2000
Instead: /message "I play FiveM" 2000

Add table.concat
