awsmobile init报错含us-east-1？配置us-east-2仍遇非法字符错误

Hey there, let's break down the likely reasons behind your frustrating error when running awsmobile init, even after configuring for us-east-2:

1. Stale Configuration Cache Is Overriding Your Region Setting #

The awsmobile CLI (and the underlying AWS SDKs it uses) often caches old config data, which can ignore your new us-east-2 setup:

• Your local AWS config files (~/.aws/config and ~/.aws/credentials) might still have a default region set to us-east-1 that takes precedence. Double-check these files to make sure the default region matches us-east-2.
• If you tried initializing the project before, the local .awsmobile folder in your project directory could be holding onto old us-east-1 settings. Delete this folder entirely, then re-run awsmobile configure and awsmobile init from scratch.

2. Invalid Characters in Your IAM Credentials #

The "header content contains invalid characters" error almost always traces back to issues with your IAM access key or secret key:

• You might have accidentally copied hidden characters (like extra spaces, line breaks, or tabs) when pasting your credentials. Try manually typing the access key and secret key instead of copying to avoid this.
• While rare, if your credentials have non-ASCII characters (which shouldn’t happen with AWS-generated keys), this will break the authentication header. Regenerate a fresh set of IAM credentials from the AWS Console and use those instead.

3. Outdated awsmobile CLI Version #

Older versions of the awsmobile CLI have known bugs with region handling and credential parsing:

• Run awsmobile --version to check your current version. If it’s not the latest, upgrade it with this command:

  npm install -g awsmobile-cli
  

  After upgrading, re-configure and re-initialize your project to see if the issue clears up.
