I have been working on a module for 2 months. Right up till now, my module was working perfectly. But now when I installed a new module and updated the schema, the following error came from the module I was working on before.
File "/usr/lib/python3.6/xml/sax/expatreader.py", line 111, in parse

I looked through the XML file causing this error multiple times but there was nothing wrong with it and the module was working perfectly before.
I then proceeded to create a new virtual environment for Tryton, reinstall trytond and use a new database but the same error popped up again.
Please help.
P.S. the new module has nothing to do with the old module (no common dependencies, and they do not depend upon each other), and the new module and all other modules are working perfectly except for the old module
