Invalid value for type in block 'main-product-personalisation'.

[AjitGoel]

I am trying to make the changes shown below in the screenshot. To do this, I have created a liquid template file and updated the template/product.json file to use the type from the liquid template file. When trying to save the template/product.json file shopify is throwing "Invalid value for type in block 'main-product-personalisation'" error. What am I missing? 

snippets/main-product-personalisation.liquid:

<div class="product__description rte quick-add-hidden">
  some text and plan to add a textbox control
</div>

template/product.json

    "sections": {
        "main": {

                    }
                },
                "main-product-personalisation": {

hello there  

It looks like you're trying to create a custom block type in your Shopify store and are running into an error when trying to save the template/product.json file.

The error message you received - "Invalid value for type in block 'main-product-personalisation'" - suggests that there may be an issue with the way you've defined the "main-product-personalisation" block type in your template/product.json file.

• Make sure that you've uploaded the liquid template file to your Shopify store and that it is properly linked to the "custom_liquid" setting for the "2075f96e-ebee-4a0c-8e77-22c4790af4e0" block.
