App crashes every few days

💬 App Building

Hey, I'm also experiencing issues with my app. It crashes unexpectedly every few days. My current workaround is to restore previous versions, but this has caused me to lose significant work. How can I solve this?

Hi @PaulaG,

Thanks for reaching out. I can look into it internally, but I'm having trouble tracking down your account. Could you share the subdomain or the email you use to log in?

Thanks. I see that connections were maxed out around 2:15 pm PT yesterday.

Were there any heavy queries or workflows running around that time? Were you connecting to the database externally using a connection string?

Are you currently able to access the database?

Also, can you share more details about the behavior you're seeing? I would expect queries to stop triggering successfully when connections are maxed out. When the app crashes, are you seeing query errors or queries hanging?

I was connecting a module to the app, which initially worked fine until I added another input for the module to run based on a selected cell from a table within the app. After making this change, the issue began.

My workaround was restoring a previous version of the app, but unfortunately, this caused the loss of all the recent modifications I made, especially the integration of the module. I tried recovering various past versions to minimize lost work, but none resolved the issue. Even after recovering an older version from approximately a month ago, the app is visible in public and user views, but still won't appear correctly in edit mode—it just displays a blank screen.

Regarding the database, we’re using BigQuery, and I can currently access it without issues. Other Retool apps we have that use the same database connection are functioning normally.

If helpful, I can privately share a screen recording illustrating the issue. Let me know how you'd prefer to proceed!

Hi @PaulaG,

Yes, you can send a screen recording via DM.

I will also split this into a new topic since it sounds slightly different (though maybe related).

Can you also DM me the app json?

Thanks! I already DM you. Let me know if you need additional info.

For any folks following along or running into similar issues, this was a Retool bug, and our on call engineering team shipped a fix :slightly_smiling_face: :white_check_mark:
