i have skipped the domain purchase chapter  
I replaced it with the domain shown to me  
As shown in the picture  
How can I activate it without buying a domain?

You can just remove the domain code from there.

I’m getting this error when running the npx sst deploy --stage prod command:

prod-notes-ApiStack failed: The following context variables are not supported: [$context.identity.cognitoIdentityId] (Service: AmazonApiGatewayV2; Status Code: 400; Error Code: BadRequestException; Request ID: 5aef6cdd-a10e-4abc-bd0c-08040632e4e6; Proxy: null)

Then it rolls back all resource creation.  
Thanks for any help
