Error in codebook generation: "Error: Failed to make codebook because XPath evaluation: cannot handle function 'once'."

I have downloaded Task Force LINKS Codebook v1.1
from https://nafundi.com/blog/posts/nafundi-and-task-force-release-codebook-generator-for-odk/
and tried to use it to generate a codebook from my .xml file from XLSForm.
I selected my .xml form but when I click "2. Make codebook" I receive the
below error:

Error: Failed to make codebook because XPath evaluation: cannot handle
function 'once'.

Any advice? Thanks.

Hi Brett,

There isn't any remaining funding from Task Force to support changes
to the codebook program. If your organization finds it useful and
would like to make improvements, let me know and I can try to put
together a coalition of the willing.

Until then, please file this as an issue at
https://bitbucket.org/tfgh/codebook/issues.
