Form Submission Type: 'Send Email' returns 'Malformed Request Syntax'
I'm currently learning AEM forms and trying to submit a simple form that sends an email after submission. The form takes a name and email address. The Day CQ Mail service is configured on my local Author instance which is where I'm testing. Any help or reasoning as to why I'm getting 'Malformed Request Syntax' is greatly appreciated. Reference images are below. Thank you!
