Challenge:
Sometimes capture validation form might throw this error after importing the package to new environments or even during the development.
“Failure creation <document_form name> TypeError: C is not a constructor”
Solution:
This might be due to the some missed internal elements of the package. For eg: – KTA might have missed global variables. Or some other issue like Java scripting compile issue.
In this case, just open document form and click Preview. This will give more details about the error. The Same can be tried on activity form.
