> Hey Sam, Instead of using a dummy query, I would recommend switching to an expression structure binding. You can have many inputs to the binding and use a single script transform. To make it poll, make one of the inputs a now(x) where x is the time, in milliseconds you want the poll rate to be

to make a list and append to it the dictionary and now I'm closer I think but I get a "Cannot read properties of undefined (reading 'content')"
