Error during adding a new screen

Hi everyone,

I am just starting with App Inventor. I do not have clue, why I receive an error message, when I try to add a new screen.

Technical Data to be Submitted:

notes = Browser: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:121.0) Gecko/20100101 Firefox/121.0
foundIn = nb195c
faultData = (TypeError) : b.a.k is undefined

Can anyone give me a hint what is going wrong here? I tried a different browser (Edge), but it did not work.


A post was merged into an existing topic: CustomWebView : An extended form of Web Viewer

What name did you try to give your new screen?

Export your .aia file and upload it here.

Hi everyone

I have the same error:
"notes = Browser: Mozilla/5.0 (X11; Linux x86_64; rv:121.0) Gecko/20100101 Firefox/121.0
foundIn = nb195d
faultData = (TypeError) : b.a.k is undefined
projectId = 4979497895854080"

I had been using appinventor 2 without any problems. I've been getting this error for a day now.
I reproduce the error with only the following:
* I create a new project "test_error".
* Without adding anything to the initial screen, I add a new screen with its default name.
* The error appears immediately.

I did the same thing again, but adding a label before creating a new screen (in case the empty screen causes problems):

 * I create a new project "test_error_con_label".
 * Add a label to Screen1
 * Added a new screen with its default name.
 * The error appears immediately.

I did not try with another browser (I see that they match Julian_Ha)

I attach the .aia

test_error_with_label.aia (1.7 KB)
test_error.aia (1.5 KB)

Confirmed in Brave browser.

Same as here Chrome/Firefox

We have a fix in the works. It should be deployed over the weekend.
