Seeing the unable to deploy error message

[Zere0913]

Hi Kal, how are you doing? I am coming with other problem looking for your support. Please see the below notification while I tried to deploy a form…

unable to deploy

your form cannot be deployed because it contains errors:

Unexpected KoBoCAT error 400: b’{“detail”:“There has been a problem trying to replace ${undefined} with the XPath to the survey element named 'undefined'. There is no survey element with this name.”}’
