Magento 2: this.options.jsonConfig.mappedAttributes is undefined

Configurable products are not changing the pictures while selecting attributes like size or color.
I really don’t know how to fix this problem. It is two days now and I still facing the same issue.

I noticed while I click on the attribute, it’s giving me this error on the swatches-renderer.js.

this.options.jsonConfig.mappedAttributes is undefined

This is the default swatches-renderer of Magento 2.3.3, not a custom one from the theme.

Can you please help me with that?
PS, I’m on Magento 2.3.3

Thanks!
