500 error on running serverless invoke local

When running

$ serverless invoke local --function create --path mocks/create-event.json from https://serverless-stack.com/chapters/add-a-create-note-api.html

I get

{
    "statusCode": 500,
    "headers": {
        "Access-Control-Allow-Origin": "*",
        "Access-Control-Allow-Credentials": true
    },
    "body": "{\"status\":false}"
}

I added a log and get: { UnrecognizedClientException: The security token included in the request is invalid.

I had this error. It was because I forgot to create the table in DynamoDB

Yup , get same error:

   [7] external "babel-runtime/core-js/json/stringify" 42 bytes {0} [not cacheable]
{ UnrecognizedClientException: The security token included in the request is invalid.

provider:
  name: aws
  runtime: nodejs6.10
  stage: prod
  region: eu-west-2
  profile: personal

and in ~/.aws/credentials:

[personal]
aws_access_key_id

for some reasons image uploads dont work

Found the following steps to be the solution to the exact problem -

1. Remove the current aws config and credentials by : sudo rm ~/.aws/config and sudo rm ~/.aws/credentials
2. Recreate an access key for the User, from the IAM Console
3. Reconfigure your AWS CLI with aws configure and make sure you put the correct region

Worked for me!
