Today my app suddenly stopped working on both web preview testing and the thunkable live app. When investigating I found that the data viewer is now crashing the app whenever it is refreshed. I’ve tested this on a new project with just a data viewer and a refresh button and it crashes instantly. ---

Yes, I figured out it was the data viewer and to test that I created a test file that I linked up above. It still does not work. The test file only has a data viewer and one button and still crashes. If that test project above works for you then I’m out of ideas. I even cleared the cache on my browser. ---

Can you share a different [minimal](https://community.thunkable.com/t/why-thunkables-team-asks-for-minimal-examples-and-what-they-are/1669259) example. I am unable to open the project you shared. Could you also share a screenshot of the offending blocks that when you run are crashing the app? Are you by chance adding any null values into the table? ---

Can you test this block setup and please make sure you’re on the latest version of the companion app? If you notice I just rearranged how your blocks were set and I removed the wait blocks ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/3/6/3682c07ae57885147082c437c0f005a2a7fa690c.jpeg) ---

It still crashes. It’s the oddest thing, this morning all of my pages looked blank then that got fixed and now this problem. I have restarted my computer, I have uninstalled and reinstalled the mobile app, and I have signed out and signed back in and I still can’t figure this out. So that test project worked for you? Edit: I even installed chrome to see if it worked on a different browser. I’m running Windows 11 ---

I encounter the same issue. I debugged my app and can confirm that when the refresh block is included my App crashes - if I delete it my App works fine. ---

Hi All I have a similar issue, the app works with the Data Viewer refresh call in the Live Test App but crashes when the app is tested on TestFlight (on iOS); resulting in a blank white screen Previous versions of the app, uploaded before 11/8/2022; worked properly. I have also removed the refresh block from a new build on TestFlight and the app works correctly now; indicating there is some error in the refresh call in the backend/object code. Something to look into? Kind regards David ---

Hi everyone - I am experiencing this same issue with my app; earlier I thought my DVL had corrupted or something, so I tried replacing it with a new DVL - but the issue is still there. **Device** - Galaxy A50 **Mode** - Thunkable Live (v327-1) The app just crashes, and shows this - ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/f/a/fa8784033c0b7aaff1b182f90c76ec5c1ad70879.png) This is a relatively new bug, I can assure this wasn’t there until last week I think… @jared please look into this 🙂 ---

Is there any solution yet? I tried lots of combination. If i created new page and add same blocks they are working but it was really hard. It must to be easy solution. I also tried to delete blocks not working same issue for some pages. [Next page](https://community.thunkable.com/t/solved-data-viewer-crashes-app-when-refreshed-aug-2022/1996700.md?page=2)
