sam local start-api fails with "The security token included in the request is invalid"

Description:

I have a small API which uses a KMS key to encrypt and decrypt strings. The API works exactly as expected when deployed to AWS, but fails when run locally with “The security token included in the request is invalid”.

There are several bugs that have variations on this theme, but all of them are at least six months old. I’m opening this one to address it in newer versions of SAM / the nodejs Docker image.

Steps to reproduce:

• Download and unzip the encryption-test.zip file
• Follow the instructions in the “Deploying” section of the readme to deploy the API to AWS
• Follow the instructions in the “Running locally” section of the readme to run the API locally
• Run the following two curl commands:

$ curl \
    --location \
    --request POST \
    'https://<your-api-id>.execute-api.<region>.amazonaws.com/stage/encrypt' \
    --header 'Content-Type: application/json' \
    --data-raw '{
        "data": "hello"
    }'

and

curl \
    --location \
    --request POST \
    'http://127.0.0.1:3000/encrypt' \
    --header 'Content-Type: application/json' \
    --data-raw '{
        "data": "hello"
    }'

The first one (the one that points to AWS) will succeed, but the second one will fail.

Observed result:

Expected result:

Making the curl call against sam local start-api should work the same as against API Gateway.

Additional environment details (Ex: Windows, Mac, Amazon Linux etc)

1. OS: macos Moterrey 12.3.1
2. sam --version: SAM CLI, version 1.46.0
3. AWS region: us-east-2

I’m running nodejs 14.x with image samcli/lambda:nodejs14.x-x86_64-f88a901bbe51b578e9260ae49.

Add --debug flag to command you are running

Thanks for this!

I was able to get the sample to work using my local credentials. Closing.

Thanks for your feedback.

That is the reason why we have implemented Accelerate features. It is not possible to test all the aspects of serverless functions on your local machine. As you mentioned, we can’t assume the role that is used in the template with sam local commands. And also, we can’t provide local emulations for all other services that AWS offers.

For that reason I would highly recommend giving Accelerate a try. If you have any questions or concern please feel free to comment under this issue https://github.com/aws/aws-sam-cli/issues/3264 or create a new one.

I will keep this one until I got your feedback to see if there are any issues with emulation image that we have.
