The Windows Task Scheduler is a task scheduler in Windows that launches computer programs or scripts at pre-defined times or after specified time intervals. In this article, you will learn how to fix Windows Task Scheduler Error 0x1. Here are some related guides: Python Automation in Windows with Visual Studio Code, Run the Python Script via Task Scheduler, and How to Automate Windows Update with PowerShell and Task Scheduler. The exit code 0x1 in the Task Scheduler means an Incorrect function called or an unknown function called. The error can be difficult to solve as it is ambiguous. Here are some possible reasons for the 0x1 Error Status.
But in my case, I went through all these steps to ensure these issues are eliminated.
- The message suggests that the Task Scheduler service was unable to save the file to the network share. This could be due to a permissions issue, network connectivity issue, or some other issue related to the Task Scheduler service.
- You could try running the task with a different user account that has the necessary permissions to access the network share. Or try saving the file to a local directory instead of the network share.
- Additionally, check the network connectivity and ensure that the network share is accessible from the computer where the task is running.
Task Scheduler (0x1)
The Task Scheduler (0x1) is associated with a system path issue. When you check the task history or event logs, the task does run successfully but the actual result will never be achieved. Please see how to fix Windows Task Scheduler 0x2 Error.

Note: When you take a look at the event log, you will notice that the task was completed successfully. It becomes tricky when this is the case. But I will walk you through how to resolve this issue.

Why was this error prompted?
In my case, the issue had to do with the following parameters “Action, Program\script, Add arguments (optional), or the Start in(optional)“. In the resolution step, I will show you how t fix this task.
Resolution to 0x1 Exit Code
I will not be showing you the steps to launch the Windows Task Scheduler with images. Here is an article on it: Run Python Script via Windows Task Scheduler. Also, see how to fix Windows Task Scheduler 0x2 Error.
Open the task scheduler by clicking start and typing in “Task Scheduler”. Click to open it. Click task scheduler library, and then right-click on the required task and select the properties
On the Actions Tab, click on Edit as shown below. In the Start in (Optional) field type in the required path only. If this field is omitted, the following 0x1 Error Status will be prompted if not done correctly. Please specify the following parameters:
Action: Start a program
Program\script: [Paths o the Python executable]
Add arguments (optional): [Add command line argument if any]
Start in(optional): [Directory path where python script exist]. If omitted, 0x1 error will be prompted for a Pytho script.
Alternatively, you could specify the right path only in the Add arguments (optional) field as shown below. and this will be sufficient as well.
C:\techda\xxxx\PythonScripts\yourscript.pyYou could also determine the Python installation path via the Python interactive Shell as shown below or Command Prompt by using the Where Python command. In this case, Python was not installed from the Microsoft store. Please see this guide for an alternative step: How to run Python Script via Windows Task Scheduler“.
As you can see, the task is running. I highly recommend you see Task Scheduler Errors and Success Codes: What does the Error Code 0x41301 Mean? The Code 0x41301 simply means the task is currently running.
Re-run the scheduled task again. When this is done, the last run result is 0x0 which means the task ran successfully as shown below.
Logging and Error-Handling to Debug Task Scheduler Error 0x1
If none of these steps above works which I am pretty sure will. Kindly add an exception handler to the script to log the traceback. For example, you could use the logging module to write detailed logs to a file or add try/except blocks to catch and handle exceptions. You can see this guide for more information “Python Automation in Windows with Visual Studio Code“. To troubleshoot this issue further. You could try the following steps:
Alternatively, consider using a different scheduling tool or method to execute the script, such as a third-party scheduling tool or a Windows service. One example of a third-party scheduling tool is called "Task Scheduler Pro"Let us run with the first option to add logging and error handling to the script. For example, you could use the logging module to write detailed logs to a file or add try/except blocks to catch and handle exceptions. You can add logging to your Python script using the built-in logging module. For example, you can add try/except blocks to catch exceptions and log them to a file. Here is an example of how to do this:
import logging
# Configure logging
logging.basicConfig(filename='script.log', level=logging.DEBUG)
# Use logging to write messages to the log file
logging.debug('Starting script')
try:
# Your script code here (Copy and paste here and indent correctly)
except Exception as e:
# Handle exceptions and log the error
logging.error(str(e))In this example, logging is configured to write messages at the DEBUG level and above to a file named script.log. You can use different logging levels to control the verbosity of the logs, such as INFO, WARNING, ERROR, and CRITICAL.
Inside the try block, you can write your script code as usual. If an exception occurs, it will be caught by the except block, where you can handle the exception and log the error message using the logging.error() function.
View the log output
This will write any exceptions to a file called “script.log” in the same directory as the script. You can choose to specify a different directory if you wish. This can help you diagnose any issues that may be occurring when trying to access or write to the UNC folder. Below is the output of the logging and error handling we added to the Python script.

Note: This error occurs when Python does not detect the matplotlib library in your current environment. But with the steps above, this error was eliminated.
