Hi, I'm currently fixing the save feature of my group project, the JSON file seems to be created just fine, but when I clicked on it and tried to open it, it says that the file does not exist, it turns out that the JSON file has not been written on at all, and the error says:
Caused by: com.google.gson.JsonIOException: Failed making field 'javafx.scene.layout.HBox#biasDirty' accessible; either increase its visibility or write a custom TypeAdapter for its declaring type.
