Error " [400] Unsupported query" When Adding CV Files to Monday.com via Make.com Automation

Hi everyone,

I’m working on automating our recruitment process by creating a flow that automatically adds candidates’ CVs from email to Monday.com. Here’s my current automation setup in Make.com:

1. Email gets forwarded to Make.com (works)
2. Parse email content (to extract candidate info) (works)
3. Create new item in Monday.com board (works)
4. Add the CV file to the Monday.com item (doesn’t work)

However, when trying to add the CV file to the Monday.com File column, I keep getting this error:

[400] Unsupported query

I’ve verified that:

• The Monday.com column is set up as a File type
• I have the necessary permissions
• The integration is properly connected

Has anyone successfully set up a similar automation? Any ideas what might be causing this error?

Many thanks

Peter
