Outlook NodeApiError: were unable to deserialize

Known Issues
1

Hello everyone,

I’m currently facing an issue when posting a message on n8n (cloud version) and adding an attachment to Outlook (also cloud version). I’m encountering a “NodeApiError: were unable to deserialize” error each time I attempt to include an attachment. I’ve confirmed that the binary data is being correctly retrieved, and I’m using the correct variable name for the attachment. However, the error persists. Has anyone encountered a similar issue or have any insights on how to resolve this?

Thank you in advance for your help!

Hey @olivier_sabban,

Welcome to the community :raised_hands:

I have just given this a quick go and have managed to reproduce it and have created NODE-1223 as the internal ticket to get this fixed.
