All attributes are created, After import products, then simple products are works fine, but configurable product throw Invalid entity_type specified

I have only used product_size select attribute in configurable product.

Suggest me, why its throw error, its there any issue in my custom attribute creation.

Note: each attribute have 2000+ values.

Well, if we go through the stack trace, it is clear that the program control searches for some configuration related to Model...

I suggest you to have a look into your config.xml file where we setup resources. To be clear, in the config.xml file,

<global>
    <models>
        <namespace_modulename>
            <class>namespace_modulename_Model</class>
            <resourceModel>some_resource</resourceModel>
        </namespace_modulename>
        <some_resource>
            <class>namespace_modulename_Model_Resource</class>
            <entities>
                # I think this is where you have to configure which tables
                # you are going to interact with in this "Model" 
                # so you have to map your table names(entities) here ....
                # please follow the link I have provided below.... 
            </entities>
        </some_resource>
    </models>
</global>

you can find detailed explanations here in alanstorm's website

I hope this would be of some help to you! :)

  • +1, but I am using magento 2 – Rajkumar .E Oct 31 '17 at 9:50
  • Really sorry, of course, what I have shared is for magento 1.x. I don't know Magento 2.x , but I think the concept would be the same in magento 2.x too. Please make some tweaks in your configuration files where you will define Models, Blocks, Helpers etc., – Velu narasimman Oct 31 '17 at 9:59
