Outlook node issue "were unable to deserialize”

Hi, since the new update I got this issue: “were unable to deserialize”.

I want to execute a outlook node to create a draft and add two attachments (docx and pdf). Before everything works fine but now it doesnt work.

Someone knows why?

I really appreciate it.

Thank you!

I think I need to downgrade the n8n version again. Because I cannot attach any attachments…
