SignatureDoesNotMatch error when using ampx sandbox command for AWS Amplify deployment

Question

I'm encountering a installation error when using "npx ampx sandbox" in Webstorm Jetbrain after " npm install amplify@latest".

```
 SignatureDoesNotMatch error when attempting to use the ampx sandbox command for deploying my AWS Amplify backend. The error message states: "The request signature we calculated does not match the signature you provided. Check your AWS Secret Access Key and signing method."
```
Can someone teach me what's the problem

Answer

Hi

The "**SignatureDoesNotMatch**" error indicates a problem with your AWS secret access key.

* Verify your AWS credentials - https://github.com/aws/aws-sdk-js/issues/86
* Re-authenticate your AWS credentials
