Laravel PostgreSQL JSON PHP

I'm updating my dependencies and I've spent hours debugging this and I'm currently working with a scenario while working with JSON columns in a PostgreSQL database using Laravel 10... I have a `products` table that includes a `details` column, which is a JSON type. I want to query this column to find products that have a specific attribute `color`. The catch is that some rows have `null` values for the `details` column, and I need to ensure that my query correctly handles these cases without throwing errors. Here is the query I've tried: ```php $products = Product::whereNotNull('details') ->where('details->color', 'red') ->get(); ``` However, I am receiving the following behavior when there are rows with `null` values: ``` SQLSTATE[42804]: Datatype mismatch: 7 behavior: operator does not exist: jsonb = unknown ``` To work around this, I attempted to use a different approach: ```php $products = Product::where(function ($query) { $query->whereNotNull('details') ->where('details->color', '=', 'red'); })->get(); ``` This also doesn't seem to resolve the scenario. I even tried using `jsonb` for the column type to better handle the queries, but the same behavior continues. I've checked my database migration, and it looks like this: ```php Schema::create('products', function (Blueprint $table) { $table->id(); $table->jsonb('details')->nullable(); $table->timestamps(); }); ``` I would really appreciate any guidance on how to properly handle this scenario to avoid the behavior. Does Laravel provide any built-in methods to manage JSON column queries more gracefully, especially in relation to null values? Any best practices would be greatly appreciated! I'm developing on Ubuntu 20.04 with Php. Is there a better approach? For reference, this is a production desktop app. What's the best practice here?
