Lower-case function is giving error

zash0012 · July 26, 2021, 7:07am

Hi,

I am using lower-case() function in hidden value but when i am rendering the form then it's giving me error.
Error: loadErrors: FormLogicError: Could not evaluate: lower-case(/model/instance[1]/data/lower_case_test), message: callNative() can't handle nodeset functions yet for lower-case()
Attach is the screenshot of the error.
Please help me to resolve this error.

Thanks & Regards,
Zeeshan Ahmad

This implies that the xpath path which you are passing to the function (/model/instance[1]/data/lower_case_test) doesn't refer to a single node, but might be a repeat or other situation where there are multiple elements at that path.

Is that the case for your data model?

I have also checked this syntax in calculate condition.
lower-case("I AM ZEESHAN")

That seems really strange. lower-case("I AM ZEESHAN") is definitely a valid XPath Expression.
I also couldn't find the Note question type that you're using here. Have you done any changes to your local CommCare version?

Yes I have changed the label to Note.
But for 'text' field it's also not working.
What are you using to render the form?

Hi @zash0012 ,

It seems like that error message is coming from Enketo, not from CommCare. You can try and file an issue with their team if you believe it is an error.

Hi @Farid_Rener,

Thank you !
I will check with Enketo.
