File "C:\Users\mister\PycharmProjects\MyFirstProjest\venv\lib\site-packages\jira\resources.py", line 173, in __getattr__
if hasattr(self, 'raw') and item in self.raw:

Perhaps your issue has no comments, so you need to test for that condition. Your syntax works for me for an issue that has at least one comment, but for an issue with no comment, I get an error, though a different one:

Traceback (most recent call last):
File "jiratest.py", line 43, in <module>
print (issue.fields.comment.comments[0])
IndexError: list index out of range

The ticket has multiple comments,

Same code is working for different project 

I don't know why is it not working with this project
