Troubleshooting HTTP API: Zapier Integration for Table Rows Issue

Hey there, I watched a few past tickets about HTTP API problems, but i didn't find the answer to my problem I want to trigger a Zapier for each row of my table and send over the linkedin url of the row, but the answer is "Failed to parse body input" What am I missing ? I tried with and without brackets it doesnt seem to do much... Thanks for your help !
