Syntax message in sql

I have a problem i don’t realy know how to fix,

CREATE TABLE `user` (
  `id` int(11) NOT NULL,
  `email` varchar(180) COLLATE utf8mb4_unicode_ci NOT NULL,
  `roles` json NOT NULL,
  `password` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci
MySQL a répondu : Documentation

#1064 - Erreur de syntaxe près de 'json NOT NULL,
  `password` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL
)' à la ligne 4

I took this sql when i exported my database in localhost, but when i try to create the User Table for my site in Production i get this Error message.

I thought it was because je ‘Json’ format for the ‘role’ but when i change it to ‘array’ i still get the same error.

Answer

Check your mysql version. Based on mysql site documentation, it say:

Prior to MySQL 8.0.13, a JSON column cannot have a non-NULL default value.
