Answer 1

Based on your error:

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

That would have come from one of the following two lines if either self.username or self.password was None (The Python 'NoneType'):

self.update_text(self.cmsemail,self.username)

self.update_text(self.cmspword,self.password)

And those lines would have an issue if one of these next lines wasn't pulling data:

username=os.getenv('USERNAME_YAML')

password=os.getenv('PASSWORD_YAML')

So I would check to see that those lines return strings, or else you'll run into the issue you had.
