First setup issue with dynamic shopOrigin

[rafaelstz]

Hi,

First of all, nice project, thank you for sharing it! I had difficulties to set it up, so if you can help I will be grateful!

I completed the installation, adding valid keys and host with my Ngrok URL but running the npm run dev in my local or uploading to Vercel I got this result below.

SerializableError: Error serializing `.shopOrigin` returned from `getServerSideProps` in "/".
Reason: `undefined` cannot be serialized as JSON. Please use `null` or omit this value.

I changed the shopOrigin to a static value to check and this below is the next issue that I'm having.

Thank you! Regards, Rafael
