To solve the "You must specify a region" error we have to set a region the command applies to.
We can specify a region for a single command by passing the
aws ec2 describe-instances --region us-east-1
To set a region that applies to all commands run by the AWS profile, we have

aws configure set region command:
aws configure set region us-east-1 --profile amplify-user-1
In this case, we've set the region of the
amplify-user-1 profile to
aws configure set region command writes the region to the AWS config file.

To check the region that's currently configured for a profile, you can run the
aws configure list command:
aws configure list --profile amplify-user-1

aws configure set region command because it applies to all of the AWS CLI
commands you issue with that profile.
You can then easily override the region for a specific command by passing the

file, and is useful for one-off commands.
