Fixing the "Uncaught TypeError: e is not a function" error in Webflow

When encountering the "Uncaught TypeError: e is not a function" error in Webflow, it means that there is an issue with a function call. Webflow uses JavaScript extensively, and this error often occurs when there is a mismatch between the expected function and the actual function being called.

Here are some steps you can take to fix this error:

Check for missing or incorrect function names: Review your code and make sure that all function names are correct and spelled correctly. Check for any missing or extra parentheses, brackets, or commas that could be causing the error.
Verify function arguments: Ensure that the correct number of arguments are being passed to the function and that they are of the expected type. If the function expects certain arguments, make sure you are providing them appropriately.
Double-check variable assignments: If the error points to a specific variable or object, ensure that it is assigned correctly and that it is of the expected type.
Inspect the stack trace: The error message usually includes a stack trace, which provides information about the sequence of function calls leading up to the error. Analyze the stack trace to identify any potential issues in the order or context of function calls.
Consider scoping issues: If you are using functions within objects or closures, check if there are any scoping issues that could lead to the error. Make sure variables are accessible within the correct scope and context.
Debugging tools: Webflow comes with a built-in Debugger that can help you identify and fix JavaScript errors. Use the debugger to step through your code, set breakpoints, and inspect variables to find the root cause of the "Uncaught TypeError" error.
Review external code: If you have included any external JavaScript libraries or plugins in your Webflow project, ensure that they are up to date and compatible with the version of Webflow you are using. In some cases, outdated or conflicting libraries can cause this type of error.

Remember to regularly save and test your changes as you progress through troubleshooting. By following these steps, you should be able to identify and resolve the "Uncaught TypeError: e is not a function" error in Webflow.
