nuBuilder Forum

Hi upgraded to 4.8 and also used this link to install the latest version https://github.com/nuBuilder/nuBuilder/ ... master.zip
I am now getting "Uncaught TypeError: Cannot read properties of undefined (reading 'slice') Please check the browser developer console for details."
when trying to add a new fast form, that is from any mysql table.

I have tried reinstalling the latest version this morning, but still getting the error.

nuBuilder Forte 4.8

DB Version: V.4.8-2025.06.12.00
Files Version: V.4.8-2025.06.12.07
(V.MajorVersion-CurrentDate.BuildNumber)

Thank you.

The error should only be temporary. After closing the browser and logging in again, it should disappear. Otherwise, use the latest nubuilder4.sql and run the database update again, and see if the error is gone.

Hi kev1n, thank you for prompt response, tried that and also full update and its still coming up with this error.

Please check the browser developer console for detail

What do you see there ?
...and which version did you update from?

Hi kev1n,
I upgraded to 4.8 then saw the post viewtopic.php?t=12529, I used the link you gave in this to upgrade again, I then discovered the "Uncaught TypeError: Cannot read properties of undefined (reading 'slice') Please check the browser developer console for details." error when running form builder so downloaded the latest version from github and ran update again to try to solve this error but still I get Uncaught TypeError.. Have closed browser completely and still get this error.

The question remains: what error is output in the developer console?

Please answer these questions

Hi kev1n in developer console I see :

Uncaught TypeError: Cannot read properties of undefined (reading 'slice')
at nuSubformRowNumber (nuform.js?ts=2025061308305243)
at nuSubformRowObject (nuform.js?ts=2025061308305228)
at HTMLDivElement.<anonymous> (<anonymous>:235:22)

at HTMLInputElement.dispatch (jquery-3.7.1.min.js:2:40035)
at v.handle (jquery-3.7.1.min.js:2:38006)

which seems to be this code:

function nuSubformRowNumber(id) {
return $('#' + id).attr('data-nu-prefix').slice(-3);
}

I moved from DB V.4.6-2025.03.08.01 and file V.4.6-2025.03.22.00 now showing as DB V.4.8-2025.06.12.00 and file V.4.8-2025.06.12.07.
Thanks for your time, sorry I took awhile replying.

nuSetFFTable() and nuEnableFFDataType() are only used inside the Form Builder. Are you seeing the error while you're working in the Form Builder?

Hi kev1n, yes only when I go into the Form Builder and select the drop down for table name then it pops up and I don't see as normal the list of fields.
