Unprocessable Entity: Received valid, but incompatible JSON input

we always get this error but the email was successful.

lib.postmark.core.PMMailUnprocessableEntityException: 'Unprocessable Entity: Received valid, but incompatible JSON input.'

this is the sample output when I printed after self.to_json_message was executed.

{'From': '[e-mail]', 'HtmlBody': 'Reports Sent (v4): 1', 'ReplyTo': '[e-mail]', 'TextBody': 'Reports Sent (v4): 1', 'To': ['[e-mail]', '[e-mail]', '[e-mail]'], 'Subject': 'Reports Sent (v4): 1'}

hope you can help… thanks.

I was having the same problem earlier today, and it turned out to be a simple mistake on my part. You need to pass in a string of comma separated email addresses for “To”, not a List of them. ‘To’: “[e-mail],[e-mail],[e-mail]”

Good catch. Moving to #35
