Spring Boot Application无法在AWS Elastic Beanstalk中进行一次身份验证

Question

I have a REST API Spring Boot application for AWS that is being developed. It has been developed on a local machine and through that local machine, we have been able to pull down live AWS data even through it was on a local machine and the URL was localhost. We have finished most of development and are ready to move it up to the cloud. However, now that we created a JAR, hosted it on AWS Elastic Beanstalk, and call the API URL, AWS now gives us a 500 Access Denied Error.

Currently, our local application was being authenticated through variables in the application.properties file of our project. Those seem to not apply in the cloud environment. We also tried setting the environment variables in the Elastic Beanstalk to the same values that we have in our application.properties but that still returns a 500 error.

Here is our exact returned error from AWS

{
    "timestamp": "2019-07-02T20:23:31.400+0000",
    "status": 500,
    "error": "Internal Server Error",
    "message": "Access Denied (Service: S3, Status Code: 403, Request ID: 66CA2FE6CEE7A5D4)",
    "path": "/api/s3/buckets/list"
}

And here is the application.properties file where I placed the security keys

cloud.aws.credentials.accessKey=XXXXXXXXXXXXX
cloud.aws.credentials.secretKey=XXXXXXXXXXXXXXX
cloud.aws.region.static=us-east-1

I think Elastic Beanstalk might not have read/write role through which it can access S3. You won't need credentials when running in AWS, everything depends on roles (permissions)
