Hello everyone…I’m getting these integrity and confit errors during startup. Nothing seems broken. Does anyone know a fix or should i just ignore? Thanks!

This is a database script i made to trigger when database events trigger a database lockup.
# Make sure to change your database info and what instance of DB you are using (i.e. sqlite3, mysql, postgres etc...)
# This script will rotate for a total of 5 logs so you can compare previous errors with current one without taking unnecessary space
# There's no strict requirement to place it in the root directory of the server, but you have some options for where to put it:
# Root Directory: Placing the script in the root directory could work, but it's generally not recommended to clutter the root directory
# with scripts. It's better to create a specific directory for your application and put the script there.
# Custom Directory: Create a specific directory for your application, and place the script there.
# For example, you could create a directory called "my_app" or "database_error_logger" and place the script in that directory.
# Scripts Directory: Some servers have a designated directory for executable scripts.
# You might check if your server has a "scripts" directory where you can place your script.
# Regardless of the location, it's essential to consider file permissions.
# Ensure that the script has the necessary permissions to execute. You may need to use the chmod command to set the appropriate
# permissions, depending on your server's configuration.
# Lastly, consider setting up a virtual environment for your Python script to isolate dependencies and avoid conflicts with other
# applications on the server. This can help ensure that the required Python libraries are installed locally for your script
# without interfering with system-wide packages.
# This script was created by Edward Freeman and is covered under GPL V3. You can modify this script as you need
# However, you must retain this GPL V3 standard, and leave credit where credit is due to the original author.
