Debugging the Error

1. Click on the file and line number link next to the error message to open the Sources tool and locate the problematic code.

2. Check for common issues such as: Undefined variables or functions (ReferenceError). Incorrect data types (TypeError). Syntax mistakes like missing brackets or quotes (SyntaxError). Missing or inaccessible resources (NetworkError).

Fixing the Error

1. If the error is in your code: Correct the syntax or logic causing the issue. Ensure all variables and functions are properly defined and loaded. Handle errors gracefully using try-catch blocks or error-handling functions.

2. If the error is caused by a third-party script: Update the script to the latest version. Remove unused or problematic scripts. Check for compatibility issues with your code.
