I looked over the status of ECR for us-west-2 and it's not reporting any issues.

Fix ECR Login Issue in us-west-2
The 400 Bad Request error when attempting to login to ECR in us-west-2 may be due to incorrect AWS CLI configuration, region mismatch, or outdated AWS CLI version. The command used might not be properly formatted or the credentials might not have the necessary permissions for the specified region.

Verify AWS CLI Configuration
Check that your AWS CLI is configured to use the correct region (us-west-2). You can do this by running the command below to see the current configuration.
bashaws configure list - 2
Update AWS CLI
Ensure that you are using the latest version of the AWS CLI, as older versions may have bugs or incompatibilities. Update the AWS CLI using the following command.
bashpip install --upgrade awscli - 3
Login to ECR
Use the following command to login to ECR in us-west-2. Make sure to replace <aws_account_id> with your actual AWS account ID.
bashaws ecr get-login-password --region us-west-2 | docker login --username AWS --password-stdin <aws_account_id>.dkr.ecr.us-west-2.amazonaws.com - 4
Check IAM Permissions
Ensure that the IAM user or role you are using has the necessary permissions to access ECR in us-west-2. The policy should include actions like 'ecr:GetAuthorizationToken'.
bashaws iam list-attached-user-policies --user-name <your_username>
Validation
After following the steps, run the docker login command again. If successful, you should see 'Login Succeeded'. If you still encounter issues, double-check your IAM permissions and AWS CLI configuration.
