Hi @shivakrishna36 

Certainly! To resolve the "Uncaught (in promise) TypeError: 'l' is read-only" error, follow these steps:

1. Check Variable Declaration:

   • Resolution: Make sure you're using let instead of const when declaring the 'l' variable if you intend to modify it. For example:

• • let l = /* some initial value */;

• Inspect Imports and Modules:

  • Check external modules or dependencies (like 'readOnlyError.js' or 'aem-react-editable-components.js') for any attempts to modify a read-only variable. Update or report issues with those modules as needed.

• Look for Typos or Variable Mismatches:

  • Carefully review your code for typos and ensure you consistently use the correct variable name ('l') throughout your code.

• Check Babel/TypeScript Configuration:

  •  Review your Babel or TypeScript configuration to ensure it aligns with your code's intentions. Avoid treating read-only variables as mutable.

• Use Debugging Tools:

  • Utilize browser developer tools to set breakpoints and inspect your code's state at the point of the error. This helps pinpoint the issue.

• Verify React Compatibility:

  • Ensure you're using compatible versions of React and its dependencies.
