Recently updated the plugin to 1.4.4 on multiple projects, since that update we're running into the following error when submitting our form: Key "locale" is not a column name and can not be used as a filter

<form method="POST">
    {{ csrfInput() }}
    {{ redirectInput(url(product.url, { 'notify':1 })) }}
    <input type="hidden" name="action" value="craft-commerce-back-in-stock/base/register-interest">
    <input type="hidden" name="variantId" value="{{ variant.id }}">

    <label class="field_group">
        <input type="email" name="email" placeholder="Email" value="{{ cart.email ?? '' }}" required>
    </label>
    <button type="submit" class="button secondary">{{ 'button_stock_notify'|t }}</button>
</form>
