Laravel Non-static method Illuminate\Database\Eloquent\Model::update() should not be called statically

Reason:

Sometimes DB updates do not work because we are calling non-static methods statically.

We should change your approach to update the Product. We could possibly follow different ways.

Error Code

Product::update([ 'product_sku' => $product_sku,'product_name' => $product_name);

We are calling to update suddenly after the status product but must need to change it to something like

Product::where('id', $product_id)->update([ 'product_sku' => $product_sku

,'product_name' => $product_name);

or

Product::find($id)
->update([ 'product_sku' => $product_sku,'product_name' => $product_name);
