Your request is invalid or could not be processed by the service in Airtable block

Hello,
I have an issue with my workflow

Describe the problem/error/question

I am having an issue with an Airtable block called “InsertExpenses.” This workflow uploads an invoice to an Airtable table. I don’t know where the problem lies, and I have been working on it for four days without success.

What is the error message (if any)?
