Hi, I'm currently working on implementing RevenueCat in my Unity game. I used the Subtester Project as a reference, modified my code, and simplified the options. I'm currently running the Subtester Project with my modified code, but I encountered an error stating, "There is an issue with your configuration." I have shared screenshots of the error message and the modified script. I would appreciate it if someone in the community could guide me through this issue.

below is my modified script
