Uncaught TypeError: Cannot set properties of null (setting 'textContent')

In a published canvas app an uncaught error triggerd a complete reload.


Setup was a forms connected to a sharepoint list. The problematic datacard was set to type "number" and as soon as the user typed in a dot "." the reload was triggered. But only in the initial new mode of the form.


The logged Error was the following:

Uncaught TypeError: Cannot set properties of null (setting 'textContent')


Unfortunatly we don't have access to the full error anymore.


Has anyone already accounted such an error?

Hi @amertels ,


Do you have any customizations/formulas on the Text Input box, such as OnSelect, OnChange, etc. ?

Hi @v-jefferni ,


sorry I totally missed your reply. No there where no customizations on the Data Card.

It was supposed to be a simple number input.
