Credential should be scoped to a valid region error

Did some more testing. I had to set the AWS Preferences Detault Region to US East (Virginia) to get this to work. Looks like this default region is being used in calls to IAM which accepts only us-east-1.
I would classify this as a bug in the Eclipse AWS pl

I have the same problem. Trying to upload a new Lambda function to EU-west-1 and get the same error message. Also get it if I try and upload an updated Lambda function that I previously uploaded successfully some time back.

What's going on? why are we getting this error now? And how to we solve it?

See my reply to myself ... I found I had to set the Default region to US East (Virginia) in Window -> Preferences -> AWS Toolkit -> Regions.
I believe that this region is used to form the endpoint when the plugin queries IAM for roles. IAM is in US East only so the request fails if the default region is not US East.

thanks. made changes as you suggested and it works.

weird as it worked perfectly a week or 2 ago without your change. anyway just glad it's working again.

thanks for saving me a lot of wasted time

Thank you so much!
