Need Help Resolving Block Error in App Inventor

General Discussion
1

Hello everyone,

I'm currently working on an app project using App Inventor, but I've hit a roadblock with a persistent error in one of my blocks. Despite multiple attempts to troubleshoot, I can't seem to figure out what's causing the issue.

The error message I'm encountering is related to a 'list index out of bounds' error. I've tried reviewing my blocks, checking for any logical errors or inconsistencies, but I'm still unable to resolve it.
I also check this : https://community.appinventor.mit.edu/t/i-need-help-with-an-error-in-app-inventormendix But I have not found any solution

Has anyone else encountered similar errors while using App Inventor? If so, I would greatly appreciate any advice or guidance on how to debug and fix this problem.

Thank you for your time and assistance!

Are you using the ListView component? You are probably referring to a list item somewhere with an index greater than the length of the list. Show your blocks or share your project.
