According to the documentation:

  

"Two aggregate functions generating JSON values are available (MySQL 5.7.22 and later)"

You can check the version of your mysql with this query:
show variables like '%version%';

According to what you said:

  

@MarceloRafael version Mysql 5.7.17 I did not know. I'll try to update then.

Tip: checks the Mysql version of your hosting.
