- My goal: Edit apps
- Issue: Apps not loading
- Steps I've taken to troubleshoot: Log out and log in again, restart browser, revert to previous version and clear cache

Also tried on multiple browsers (Opera, Chrome and Edge) and had the same result in all of them.
Console shows the following error:
Welcome to the community, @Mateus_Mossmann! Thanks for reaching out.
Is this happening with multiple apps or one in particular? And when did you first notice the issue? Based on what you've shared, it sounds like the state of your app may have been overwritten by an empty save payload, similar to what is described here.
You mentioned above that you've already tried reverting to previous versions, but does that include using the _historyOffset URL parameter?
Hi Darren,
Thank you for your response.
This issue occurs with multiple apps. I first noticed it last Thursday (April 17, 2025).
I’ve tried using the history_offset parameter, and here’s what happens:
![historyoffset_edit1.mp4 [video-to-gif output image]](https://s5.ezgif.com/tmp/ezgif-50681ecad95cbf.gif)
It loads a previous working version, but from there, I don’t know how to restore the latest version to a functional state.
When I compared the changes between the latest version and this working version, this was the only difference:
Could this be related to the issue? Would it be possible for me to edit this CDN version to test it?
One detail I forgot to mention: When using history_offset=2 , it worked initially. However, even without publishing or making any changes, after reloading the page with history_offset=2 again, it froze and failed to load. Then, after multiple attempts, it started loading correctly once more before stopping again—as if the loading process were unstable.
Good afternoon, everyone.
We still can't access or edit our apps, and all the new apps we try to duplicate or create are encountering the same error. We have an active operation, with a network of over 300 financial transactions and daily order processing records running through Retool. Is there any channel we can contact for direct support assistance or an emergency action to regain access to our apps?
I've already escalated this internally, @Mateus_Mossmann, but you can always use our dedicated support channel, as well. It tends to specialize in account and billing issues, but can certainly be an avenue for surfacing emergent issues.
Looking at this initially, it doesn't seem to be an issue with the save state being overwritten, but I can confirm if you share the UUIDs of the affected apps. The other possibility is that these apps all include a reference to a corrupted module or similar. Does your org utilize modules?

Got it. I’ve also joined the Discord channel to follow up during office hours tomorrow, but I’ll reach out via email as well.
Among the affected apps, the most critical one is:
UUID: 0456ead6-8270-11ef-9c07-f3018b7bd96c
Currently, none of our apps use modules. The issue persists even when trying to run queries within the app—they fail to execute. Restoring to previous versions (including the very first version) leaves the app completely blank. Additionally, adding new elements (like tables or buttons) doesn’t work—they simply don’t appear.
Let me know if you need further details. Thanks for the quick escalation!
Hi @Mateus_Mossmann Following up from Retool Support to assist here. We've been able to inspect a copy of your 0456ead6-8270-11ef-9c07-f3018b7bd96c application state and identified an infinite loop in the transformaDataPagamento transformer. Deleting that transformer resolved the issue allowing the app to load. Can you try deleting that transformer then refresh your page and confirm that you see the app load as expected? You might need to give your browser a moment to recover and refresh a couple of times before you see the app load again after removing the infinite loop.

Thanks a lot Everett, deleting the transformer worked, and after deletion all the other apps started working as well!
