Unable to execute script at line 0. After Effects error: Can not run a script while a modal dialog is waiting for response

Report · Jul 15, 2017

I'm getting this error when loading some, but not all projects. This error is only incurred when clicking on the AE project file from within Windows Explorer. When the project is opened from within After Effects the projects open without error. Why? Needing a computer engineering degree appears to be a prerequisite for working with the Adobe apps.

This is yet another neverending workflow stopper for folks who use ScriptUI panels. Not sure what sparks it, but for some reason (usually once a day) my ScriptUI panels just stop functioning until I close the actual script panel window, open it again, get this stupid freaking message, hit OK, reopen the panel and it works again. Or sometimes quicker, I restart the app. Either way it kills workflow and is highly annoying. Oh and its been going on for years and I'm on a maxed out M1 Macbook Pro 16 inch, but then again it doesn't matter what machine I'm using!

my after effects has been fine for almost 2 months and suddenly this happened. now it's happened 3 times trying to exit adobe. it would spam me with it no matter how many times I click "Ok"

Oh, this is just one of those "forever" bugs that After Effects has sported for ages. Has something to do with certain scripts (for myself Keysmith and Rift) which inexplicably set this error off and I have to manually close those script UI panels, open them again, get the error again, close them and reopen so they function again. Of course having After Effects...perhaps...OH I don't know, automate this task so users aren't forever having to forever manually close and reopen scripts is just beyond the teams' capability at this point, like fixing background autosave.

I just updated my system to Sequoia 15.7.1 and start getting this error message. every time i start a new project/create new comp/create solid this error pops up. if i click "ok" and close the error window, i won't see this error for doing the same thing (new comp/new solid). once i quit the project and start a new project, the error will pops back up. I tried open with safe mode, moved sript folder to other location temporary, disable plugins, still do the same thing. if anyone have solution, please let me know.

just installed older version of v25 (v25.4, v25.3) it still gets error. opened v24.6.8 also gets same error. v23.6.9 didn't get the error. I opened my older projects and create a new comp and add new solid that didn't trigger the error.

also just found out the error message only triggers when i use the shortcut "command +y" i tried create solid from script, using menu/Layer/New/solid, or right click on comp window and select New/solid, they didn't trigger error pop up message.

The bug is specifically tied to the keyboard shortcut handler in AE 24+ (including 25.5).

The shortcut is internally triggering the modal dialog in a slightly different context, which conflicts with AE’s scripting/UI event loop in new projects.

The UI path (menu/right-click) bypasses that conflict, which is why it works normally there.

hope adobe developers can look into it.

thanks,
