AWS Credentials for lambda when working with scala not working

AWS lambda function does not work when attempting to work with credentials provided using the DefaultCredentialProvider.

I need to pass the credentials to S3 for it to run.

Code

def initializeAwsCredentials():AWSCredentials = {

    var credentials: AWSCredentials  = null

    try {

      credentials = new ProfileCredentialsProvider().getCredentials

    } catch {

      case e: Exception => {

        throw new AmazonClientException(

          "Cannot load the credentials from the credential profiles file. " +

            "Please make sure that your credentials file is at the correct " +

            "location (~/.aws/credentials), and is in valid format.",

          e);

      }



    }

    return credentials

  }



 def buildS3API(credentials: AWSCredentials): AmazonS3 = {

  new AmazonS3Client(credentials)

}



// inside handle request

val credentials = initializeAwsCredentials()

println("Credetials have been retrieved successfully")



println("Build S3 API using the constructor provided")

val s3 = buildS3API(credentials)

s3.setRegion(region)

println("S3 API is now available")
