ValueError: 'unknown' is not supported

The ValueError is raised because the value 'unknown' is not supported in the current context. This means the code you're using doesn't expect or handle 'unknown' as a valid input.

To fix this, you need to:

1. Identify the source of the error: Check the code where the ValueError is being raised. This will likely involve reviewing the function or method where the 'unknown' value is being passed.
2. Understand the expected values: Review the documentation or code comments to see what values are valid inputs for the function or method.
3. Handle the unexpected value: You can choose to:
   • Replace the value: If 'unknown' is a common occurrence, replace it with a default value.
   • Raise a more specific error: Provide more context about the error to help with debugging.
   • Add a conditional check: If 'unknown' is an acceptable value, add a conditional check to handle it correctly.

By understanding the context and expected values, you can resolve the ValueError by either changing the input or handling the 'unknown' value appropriately.
