Hello,

We are trying to use junos-eznc 2.6.6 to upgrade a fleet of EX4300s but we are encountering the following traceback:

lxml.etree.XMLSyntaxError: PCDATA invalid Char value 12, line 123, column 296

The target version we are attempting the upgrade for is 21.4R3-S2.4 any clues as why this is happening?
