Fix UnboundLocalError
in Panel
✅ Solution
The UnboundLocalError occurs when a variable is referenced before it has been assigned a value within its scope, often inside a function. Ensure the variable is assigned a value before being used, especially within conditional statements or loops, by initializing it to a default value like None or an empty list before the conditional block containing its use.
