Error on amazon SES: SendEmail operation: Illegal addres

Although it isn't applicable to this question, in my case, I was trying to send emails to multiple addresses at the same time.

Having a single email address here helped.

'ToAddresses': [
            '[email protected]',
        ],

Try to remove the following:

    ReplyToAddresses=[],
    ReturnPath='',
    ReturnPathArn='',
    SourceArn='',

Apparently they can't be empty!
