Extension template references invalid renderer package please contact Shopify for help.

I tried to serve my extension today after updating shopify-cli and got this error:

Extension template references invalid renderer package please contact Shopify for help.

I even try to create a new product extension and I get the same error.

I get EXACTLY the same issue. 

I have just fixed by update to last version of Shopify CLI.
