Hey @stevenmw I've updated the formatting in your post and you have an error in your last migration (the one for the invoices_products table).

You are using Schema::table instead of Schema::create and that is causing the Exception.

Change it to this and it should work:

    public function up()
    {
        Schema::create('invoices_products', function (Blueprint $table) {
            $table->id();
            $table->foreignId('invoice_id')->constrained('invoices');
            $table->foreignId('product_id')->constrained('products');
            $table->string('subject')->nullable();
            $table->bigInteger('price')->nullable();
            $table->bigInteger('quantity')->nullable();
        });
    }
