Issue with new Retool Runtime

We were excited to try the new retool runtime (App performance best practices) however we are running into a blocking issue.

We currently register global functions in Settings -> Advanced -> Preloaded JavaScript. These global functions are bound to the window object.

When using old runtime, the global functions are available and work. However, in the new runtime, these functions are not found.

Hi thanks for reaching out. Can we (retool) have your permission to log in and take a look at the app in question?

Hi there - just checking in - any chance you guys have released a fix?

Not yet, We are going through some QA to make sure it won't break other parts of retool. I will let you know when we deploy the fix.

I upgraded our apps and ran into some more weird issues. Unfortunately, I don't know if I'll have the time to isolate these to the point where it's actionable. Migrating back to the legacy for now.

Hi, do you mind describing the issues? we are happy to investigate the cause if you give us permission to take a look at the app.

Sure, do you mind if we follow up via email? My email is
