Create & Read Email Files Utilities

Michael Chirlin

Hi Michael,

Thanks for upgrading the plug-in to the Jakarta library.

After the Appian version upgraded to 22.3; I upgraded this plug-in to the 2.0.0 version.
And 'Create Email File' service does not work and throws the following error: jakarta.mail.MessagingException: MIME part of type "multipart/mixed; " contains object of type java.lang.String instead of MimeMultipart

Please assist.


Here is detailed logs:

Hi Arpit.

I think you have the value "multipart/mixed; " setted in your node input variable 'Content Type'.

I saw the following in javax doc:

So I think you should try to execute the node with "" value in your node input variable 'Content Type'. 

Hello Arpit Pipersaniya, 

I have the same issue that you say in your reply. Have you found any solution to that "There was an error creating the note" exception?
