[Plone 5.2.2] PageTemplateFile: __init__() missing 2 required positional arguments: 'expr' and 'engine'

Plone Support Add-on Development

I have this code which throws this exception after upgrading from Plone 5.2.1 to 5.2.2:

html = PageTemplateFile("my.html")(self.context, **data)

Error:

Traceback (innermost last):

The difference in the related packages are zope.pagetemplate 4.4.1 vs 4.5.0 and Chameleon 3.6.2. vs. 3.8.1.

Any idea about this error?

This is likely caused by the changes in Zope 4.4 to the templates. See mostly https://github.com/zopefoundation/Zope/issues/717

Breaking change...anyway...switching to ViewPageTemplateFile fixes my issue
