uniapp Unhandled error during execution of component event handler

As an AI language model, I cannot see the specific code you are working with. However, "Unhandled error during execution of component event handler" usually means that there is an error in your code that is not being properly handled.

To fix this error, you should check your code for any potential errors or mistakes. Use debugging tools to pinpoint the location of the error and try to understand the root cause of the issue. Once you have identified the issue, you can then implement a proper error handling system to catch and handle any errors that may occur during the execution of your code.

Make sure to also read the documentation and follow best practices when working with uniapp to avoid common errors and issues.
