I cd into the directory where all the pem/key files are and run the following:
aws iam upload-server-certificate 
    --server-certificate-name certificate_name 
    --certificate-body file://webservercertificate.pem  
    --private-key file://server.key   
    --certificate-chain file://certificate_chain_file.pem 
I get the following error:
A client error (InvalidClientTokenId) occurred when calling the UploadServerCertificate operation: The security token included in the request is invalid.
I have 1 'user' in 'users'. That user has been assigned the following permissions:
IAMFullAccess IAMReadOnlyAccess IAMUserSSHKeys
I've downloaded the credentials for this user and put them into my user variables
AWS_ACCESS_KEY ****
AWS_SECRET_KEY ****
I have 1 role on my elastic beanstalk  aws-elasticbeanstalk-ec2-role
