Reason
In a NetSuite account, we can create multiple domains. But SSL certificate implementation can only be done for a single account. So, if we tried to set up our SCA website locally, it will show an error in the console as given below:

Solution
For this situation, we can use a secured domain (SSL Certified) Domain for local running.
The Structure needs to be followed:
https://<Secured domain name>/<URL ROOT>/shopping-local.ssp
For Secured domain: Goto commerce >> Hosting >> Domains – https domain
For URL Root: Goto commerce >> Hosting >> SSP Applications – URL root of corresponding SSP Folder Created.
