Strange issue with cognito

[gator1]

I am trying a program from a class on Plursight. It uses cognito's UserPool. The program would fail
with a message like this.

The request signature we calculated does not match the signature you provided. Check your AWS Secret Access Key and signing method. Consult the service documentation for details.

This can be reproed with awscli as follows:

aws cognito-idp admin-get-user --username somebody --user-pool-id us-west-2_pem5bqKBX

I would get
An error occurred (InvalidSignatureException) when calling the AdminGetUser operation: The request signature we calculated does not match the signature you provided. Check your AWS Secret Access Key and signing method. Consult the service documentation for details.

However when I use another Macbook (older), everything works. I use the same aws account, same userPool.

Here is the info about my two machines:

The working one is Sierra 10.12, the bad one is Sierra 10.12.4

The cli: working one
aws-cli/1.14.17 Python/2.7.10 Darwin/16.0.0 botocore/1.8.21

not working
aws-cli/1.14.17 Python/2.7.10 Darwin/16.5.0 botocore/1.8.21

I am using the same key and env. aws configure returns the same thing on both machines.

There's nothing offhand that I'm aware of that would cause differences between different versions of MacOS. I would double check your secret key again just to be sure. Here's a few other things I would try:

1. On the machine that is not working, do other service commands work? i.e try aws iam list-users and a few other services. If none of the calls work that suggests your access_key/secret_access_key are incorrect.

2. If you still are seeing issues, please share a sanitized --debug log with us so we can further troubleshoot.
