Email sending is leaving the path of the attachments in the body of the email

I would like some help! I made a class to send e-mails in my application, where reports will be generated to be sent in PDF and XML format, but the e-mail is being sent with the path of the files in the body of the e-mail. and in my code there is no action where it is done.

Does anyone have any idea what it can be?
