Unable to view or deploy form after uploading XLS form

Hello all,

I am new to KoBo - trying the switch from ODK Aggregate/Collect. I have created a XLS form (that works fine on ODK Collect), uploaded it to KoBo server without problem but unable to view it or deploy it.

When deploying, I get the Server Error 500.

When trying to view, it gets stuck on the loading screen, with the message “sequence item 1: expected string or Unicode, NoneType found” at the bottom of the screen.

Can you please help to solve this issue/know where it comes from?

The XLS form created can be viewed here sample XLS form

Many thanks

Hi @effy1988,

Welcome to the community! Looking at your xlsform, i saw that you had only one language in your survey form and had labelled them with ::Francais as shown in the image below.

In KoBoToolbox, you do not have to use ::Francais if you have only one language in your survey form. However this is compulsory if you have more than one language.

For more details, you could have a look at the support article listed below:

Please have a look at your xlsform that should work now:

Object of type 'NoneType' has no len()

Many thanks @Kal_Lam ! Sorry I had forgot to answer… Very helpful, as all the other answers on the forum!
