This might be more of a Make.com question, but I'm curious if anyone has run into this...
I'm able to make a successful List Records request, with an empty request body, but after adding filter JSON to the body I get a 400 error instead.
Oddly, I can make the same exact request in Postman and receive the data I need without any errors...which tells me there are no issues with the JSON body that I'm sending.
