Error Parsing Body - POST Attachment

Trello

Hi there,

I’m trying to link a power automate flow to Trello, posting an attachment to a card. However, using the API I’m getting the error: “Error Parsing Body”. I’ve uploaded an example of the setup. Any help would be greatly appreciated.

The api works in Postman but not power automate - any tips? Thanks
