AttributeError: 'NoneType' object has no attribute 'filelist'

I'm new to this module. I tried exactly your example but it says below exception:

Traceback (most recent call last):
File "/Users/mac/Downloads/BBEditRunTemp-test.py", line 6, in
document.write('output.docx')
File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/mailmerge.py", line 121, in write
for zi in self.zip.filelist:
AttributeError: 'NoneType' object has no attribute 'filelist'

The code is here:
from mailmerge import MailMerge
with MailMerge('input.docx') as document:
...
document.merge(field1='docx Mail Merge',
field2='Can be used for merging docx documents')
document.write('output.docx')

Instead of using with to open the existing document, use MailMerge function to read the file object.
To fix the error use the below code:

from mailmerge import MailMerge
document = MailMerge('input.docx')
document.merge(field1='docx Mail Merge', field2='Can be used for merging docx documents')
document.write('output.docx')
