answer:CODEMASTER: I apologize for the mistake. The error is occurring because the username_input variable is not defined in the core code. To fix this issue, please modify the code as follows: 1. Update the following line at the beginning of the core code to import the necessary classes from the PyQt5.QtWidgets module: ``` from PyQt5.QtWidgets import QApplication, QWidget, QVBoxLayout, QLabel, QLineEdit ``` 2. Create a QApplication object by adding the following lines of code after importing logging: ``` # Create a QApplication object app = QApplication(sys.argv) ``` 3. Wrap the entire core code with the QApplication event loop by adding the following line before the try statement: ``` # Start the QApplication event loop app.exec_() ``` 4. Modify the code to retrieve the username and password from the UI input fields in the same way as for step 1. Here is the updated code for that section: ``` # Get the METRC username and password from the UI input fields username = app.activeWindow().findChild(QLineEdit, 'username_input').text() password = app.activeWindow().findChild(QLineEdit, 'password_input').text() ``` Please ensure that you make these updates in your code to avoid the "NameError" exception raised by the previous version of the code.

answer:CODEMASTER: I apologize for my mistake. The error is occurring because the single quote used at the end of 'username_input is not a regular single quote, but instead a different type of quote. It looks like a so-called "smart quote" or “curly quote”. Please try replacing it with a regular single quote by typing the code character manually instead of copying and pasting it, as some text editors or word processors may use smart quotes instead of regular quotes. Here is the corrected style of quotes used for the modified code: ``` # Get the METRC username and password from the UI input fields username = app.activeWindow().findChild(QLineEdit, 'username_input').text() password = app.activeWindow().findChild(QLineEdit, 'password_input').text() ``` Please replace the original code with this modified code and let me know if it works or if you encounter any further issues.

answer:CODEMASTER: I apologize for the mistake. The NameError you are seeing is because the app variable, which is defined in the modified code, is not defined in the scope of the core code. To fix this issue, you will need to instantiate the QApplication object and define it in the global scope. Here is an updated core code segment starting from the beginning: ``` # Import necessary libraries and classes from PyQt5.QtWidgets import QApplication, QWidget, QVBoxLayout, QLabel, QLineEdit import os import time import logging from selenium import webdriver from selenium.webdriver.chrome.service import Service from webdriver_manager.chrome import ChromeDriverManager from selenium.webdriver.common.by import By from selenium.webdriver.support.ui import WebDriverWait from selenium.webdriver.support import expected_conditions as EC import sys # Instantiate the QApplication object in the global scope app = QApplication(sys.argv) # Read credentials from UI input fields username = app.activeWindow().findChild(QLineEdit, 'username_input').text() password = app.activeWindow().findChild(QLineEdit, 'password_input').text() # Configure logging logging.basicConfig(filename='metrc_automation.log', level=logging.INFO, format='%(asctime)s - %(levelname)s:
