Apple Health file error: Bad xml

Every month I export the health file for processing in a Jupyter notebook. Today I got this error message which I believe indicates malformed xml in the export.xml file:

File "<string>", line 156

XMLSyntaxError: ATTLIST: no name for Attribute, line 156, column 1

On opening the same file in safari I got this:

This page contains the following errors:

error on line 156 at column 1: ATTLIST: no name for Attribute

error on line 206 at column 3: internal error: xmlParseInternalSubset: error detected in Markup declaration

Is there anything I can fix or should this be thrown into Apple's lap?
