Starting project with Invalid AWS Region throws a opaque error

Context:

Discord Thread The first time setup with SST/Ion was trying to follow up the examples on https://ion.sst.dev/docs/start/aws/api/ and the sst dev command was throwing an error:

SST Version

SST ❍ ion 0.0.292

Software Version (does not seem relevant for the issue)

Mac Sonoma 14.4.1 (23E224)
Node v21.7.3
npm 10.5.2

Steps to reproduce:

Run AWS Configure
- Set AWS Access Key ID as your desired value
- Set AWS Secret Access Key your desired value
- Set AWS Region to a typo e.g: ^A (CTRL+A)
Fresh install of SST and create new project
Run sst dev

OP: Now that I understand the root cause of what was causing my issue was an invalid AWS Configuration because of a typo, alternatives, and similar errors are produced when using valid string values but that are still invalid aws Zones e.g

Following steps to reproduce but using test as a AWS region You might get this output:

Error initializing aws:
   operation error SSM: GetParameter, https response error StatusCode: 0, RequestID: , request send failed, Post "https://ssm.test.amazonaws.com/": dial tcp: lookup ssm.test.amazonaws.com: no such host

// LOG:
ERROR msg="exited with error" err="Error initializing aws:\n   operation error SSM: GetParameter, https response error StatusCode: 0, RequestID: , request send failed, Post \"https://ssm.test.amazonaws.com/\": dial tcp: lookup ssm.test.amazonaws.com: no such host"

What solved the issue for me

In case it was not clear, this was solved by setting the AWS Region to a valid value such as us-east-1 in case it helps you out to quickly get you out of this problem.

Actions Required (?)

I'm unsure if this issue deserves any action but @jayair mentioned that probably we could handle this better as the error is pretty opaque, from my perspective, I was entirely sure that my aws config was good as I was looking at the wrong .aws/credentials file and at the end a very basic error put me off track.
