I have followed this great tutorial for creating and sending digital certificates to event participants (https://techcommunity.microsoft.com/t5/educator-developer-blog/send-digital-certificate-to-event-par...), and everything worked except for the last step which is sending the email with the certificate attached. I am able to receive an email with the pdf attached however, the file is corrupted and I'm unable to open it. When I check the pdf file in my share point it is not corrupted so the issue seems to be in the step of sending the email.
I tried using base64ToBinary(base64(body('Convert_file'))), when I added this I was able to open the pdf attachment but the pdf was empty and the content was erased. Please let me know if there is any way to overcome this issue.
