Time limit on cart items

I’m getting there slowly…

After spending too much time trying to make the true/false properties send to Integromat I created a new property: Paid?0=false,1=true and just marked the fields either 0 or 1. I had also been watching an old tutorial by Patick Ford on Youtube about using a workaround for a webhook before customer actions were released - there’s obviously a much better way now!

I’m now at the stage where I think I’m sending the correct data from Adalo to Integromat. My scenario runs up until the data passes successfully through the ‘Paid?’ filter and into the ‘Update Record’ Adalo module - where it fails with " RuntimeError [400] Request failed with status code 500". I’ve added the screenshots below - can anyone help?
