Gmail automation file attachment not working

Hello everybody : )

Im facing an issue with my gmail automation. Here’s how it looks like :
Trigger : Record enter a view (i check a checkbox)
Action : Send email with attachment of my invoice

My invoice is generated automatically with zapier, zapier detects a record, creates a document from template with google docs, then upload the document (invoice) in PDF format (on airtable record).

When i try my airtable automation, the PDF file attached to the mail looks like this.

I’d like to point out that my automation doesn’t start before or at the same time as the pdf file is uploaded.

Could this be an issue with google doc ? Or directly with airtable ? Can someone help me get through this :thinking:
