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.

Thanks
