Good morning, afternoon, or evening :) depending on your location!
Hope you are well today.

The error "Cannot read properties of undefined (reading 'Persona')" typically occurs when a JavaScript function attempts to access a property of an undefined object. Here's how you can troubleshoot and resolve this issue:
Steps to Resolve:

Check the Code in the CustomCellControl:
- Review the code in the CustomCellControl component mentioned in the stack trace.
- Ensure that the Persona object is properly initialized and defined before accessing its properties.
Debug the JavaScript Code:
- Use browser developer tools (e.g., Chrome DevTools) to debug the script.
- Set breakpoints in the bundle.js file at the line causing the error (136:3157).
- Inspect the value of the Persona object at runtime to identify why it is undefined.
Verify Dependencies:
- Check if the Persona object is dependent on external libraries or data sources.
- Ensure that all required libraries are loaded and data sources are accessible.
Handle Undefined Objects Gracefully:
- Add a null or undefined check before accessing the Persona object:
  if (Persona) {
  // Access properties
  } else {
  console.error("Persona object is undefined");
  }
Update the Component Logic:
- If the Persona object is expected to be passed as a parameter, ensure that it is correctly passed from the parent component or function.
Clear Cache and Refresh:
- Clear the browser cache and refresh the application to rule out any caching issues.
