python3 gspread exception not caught

I have the following piece of code which attempts to capture a gspread.exceptions.APIError, usually as the result of a timeout of the Google spreadsheet credentials. _open_sheet requests a new set of credentials. 

def _findRow(self, entry):
''' Return row index for row which contains "entry". '''
for i in range(10):
    try:
        cell = self.worksheet.find(email)
        return cell.row
    except gspread.exceptions.CellNotFound:
        return None
    except gspread.exceptions.APIError:
        # This occurs when we get a timeout of the authentication token
        # Need to reauthenticate
        self._open_sheet()
        continue
print('Leadsheet:find:: Failed to renew authorization after 10 attempts.')
return None

and from the following stack trace the gspread.exceptions.APIError is not caught:

    "status": "UNAUTHENTICATED" 
  } 
}

Any clues as to what has gone on with this code?

Same happens with me wile I'm writing the data in excel sheet after some period of time this error appears. Once I run my script again it works fine but fails after some time.

One thing that observed was while writing data if it reaches the end of the row in that sheet and there is no further row to write then it starts to throw such error.

So you need to catch this exception as below:

    try:
        Sheet.update_cell(row, column, value="What ever value")t_term)
    except gspread.exceptions.APIError as UNAUTHENTICATED:
        print("Api error occurred for gspread due to authentication failure while writing What ever value.")
