Ever struggled with this error?
"The JSON function cannot serialize tables / objects with a nested property called ‘X’ of type ‘Polymorphic’"
Want a quick and easy solution, you are in the right place, we'll look into JSONFormat and JSON function in power apps including solving the most common errors with these

In my recent tutorials, I'm concentrating heavily on Powerapps, model-driven apps, Dataverse, and Power Platform as a whole, When I encounter an interesting defect I try to immediately post it on YouTube to make other people's lives easier. Sometimes I'll also touch Power Automate but mostly when it supports Canvas.
