Scout breaks with craft commerce v3

[jornwildenbeest]

Versions:

craft-scout: 2.3.1
craft/commerce: 3.2.8.1
craft:/cms: 3.5.14

Issue:

Scout doesn't work with commerce after updating to commerce v3, so it appears.

When I try to import craft commerce products into Algolia with this code:

    \rias\scout\ScoutIndex::create('dev_producten')
    // Scout uses this by default, so this is optional
    ->elementType(Product::class)
    // If you don't define a siteId, the primary site is used
    ->criteria(function (\craft\commerce\elements\db\ProductQuery $query) {
        return $query;
        })
    /*
    * The element gets passed into the transform function, you can omit this
    * and Scout will use the \rias\scout\ElementTransformer class instead
    */
    ->transformer(function (Product $product) {

It returns this error:

FYI: the whole site throws this error.

For some reason the function Plugin::getInstance() inside the craft\commerce\elements\Product class behaviors function returns null.
Is it possible that the ScoutIndex::index function is called before the craft commerce product class is loaded or something?

Did you find a fix for this?

[jornwildenbeest]

@brambeekman for me it was adding the following code in the beginnen of the scout.php config file.

<?php
use craft\commerce\elements\Product;
use craft\commerce\Plugin as CommercePlugin;
use craft\elements\Category;

$commerce = new CommercePlugin(0);

But I couldn't figure out what was causing the error..

[janhenckens]

Instantiating the Commerce plugin before new Product() is called in Scout does indeed fix it.
I can fix it by using a different method to check wether something is an element or not, I'll try to have a fix out by the end of the week.

Fixed in today's release!
