laravel mysql json PHP

I'm working with an scenario with inserting data into a MySQL JSON column using Laravel Eloquent. I'm running MySQL 8.0 and Laravel 8.x. The JSON column is defined in my migration like this: ```php Schema::create('users', function (Blueprint $table) { $table->id(); $table->json('settings'); $table->timestamps(); }); ``` When I attempt to insert a new user with settings as a JSON object, it sometimes ends up storing NULL instead of the expected JSON string. Here’s the code I’m using to create the user: ```php $user = new User(); $user->settings = json_encode(['theme' => 'dark', 'notifications' => true]); $user->save(); ``` But intermittently, it seems like the `settings` field gets saved as NULL instead of the JSON object. I've checked the database column type, and it is indeed set as JSON. I’ve also tried using the `->create()` method: ```php db::table('users')->create([ 'settings' => json_encode(['theme' => 'dark', 'notifications' => true]) ]); ``` This still sometimes results in NULL values. I also validated the JSON using `json_last_error()`, which shows no errors. Another thing I noticed is that when I retrieve a user right after saving, the JSON seems accessible: ```php $user = User::find(1); return $user->settings; // Returns the correct JSON object ``` ``` However, if I insert multiple records in quick succession, some of them end up with NULL values. I suspect it might be related to the way Laravel handles database transactions or possibly some race condition. I've tried wrapping the insert in a DB transaction: ```php DB::transaction(function () { $user = new User(); $user->settings = json_encode(['theme' => 'light', 'notifications' => false]); $user->save(); }); ``` But I’m still seeing the same scenario. Any insights on why this might be happening or how I could ensure that the JSON data is stored correctly every time?
