Hi,
I am trying to set up an automated flow to upload emails (including attachments) from a specific Outlook folder to a specific OneDrive folder. I have set up my flow as such:

And I am getting this error:


From what I can see, it looks like it's ok with the input but having issues with the output. I've tried looking on here and elsewhere online and either I'm searching wrong or this isn't a common issue or use case.
Could anyone please assist? This could reduce my workload by at least an hour every day if I can get this working for every folder!
Cheers,
