Is Mturk endpoint only in us-east-1?

[shubhamagarwal92]

Hi @jcjohnson ,

Thanks for this cool repo. :)

I want to know if the region that we specify for AMT is fixed for us-east-1. I see that you have the enpoint_url hardcoded for us-east-1.

If I don't mention the region at all, I get:

botocore.exceptions.NoRegionError: You must specify a region

But, if I mention my default region as us-west-1 (using aws configure), I am getting the error as:

An error occurred (InvalidSignatureException) when calling the CreateHIT operation: Credential should be scoped to a valid region, not 'us-west-1'.

Is this the reason that we don't specify region in the config files?
