Consistent Blocks Error with Live Testing


many of my app pages have stopped working on the live testing on my phone. They work properly when I use the preview button on the computer, but when I live test on any phone (I have tried multiple) I get the error “something has gone wrong. check your blocks and reset this page.” . I have tried all the troubleshooting I can think of and spent nearly 8 hours today reprogramming most of my app and no luck. Please help!

Hi @imogenlawford1234 - happy to help. Can you please DM me with your project link so we can investigate further? I’ll follow up with more questions based on what we see!

Hi Cassandra,

The pages that had stopped working in my app (that I completely recoded yesterday) all just started working again. They were giving me errors for about 4 days and have now seemed to reset somehow. I didn’t change anything and I’m not sure why they stopped working in the first place. I guess I don’t need help anymore but thank you for offering. For future, do you know why this may have happened, or if it was a glitch with thunkable’s software or something on my end?

Hi again,

Almost just after I typed this message the screen stopped working again. I will send a link. It doesn’t even seem to be the project blocks, even when I take them all out the screen will still not work.

I have detached the screen from the rest of my project as I am building it for a company and it the idea has a patent pending. The blocks show errors only cause they are disconnected from the rest of the project, but I have tried deleting them all and the screen still shows errors.

If you cannot find the issue from this project with the screen separated, I will share the whole project because I am very desperate. Just reluctant to do so unless it is necessary.

Hi @imogenlawford1234 - while we look into isolating what might be causing your project to crash on the Live App, I suggest you use our “Publish as a Web App” functionality for your project testing needs. This works just as well, and you can see live changes on the web app as well.

I hope that helps!

I have the exact same problem, just signed up a couple of days ago. Every app I created keep crashing despite removing all the blocks! very annoying…

I think the problem is that your Drawer Navigator doesn’t have any screens assigned to it. Try dragging screens onto the Drawer Navigator in the component tree:
