The specified desired size is less than or equal to zero, which is not a valid target size for subsetting.

How to fix

1. Check your options file - locate the desiredSize value
2. Set a positive value - ensure the size is greater than zero
3. Use appropriate units - specify B, KB, MB, GB, TB, or percentage

Common Issues

Negative values: "desiredSize": "-500MB" → "desiredSize": "500MB"

Zero values: "desiredSize": "0GB" → "desiredSize": "1GB"

Missing units: "desiredSize": "0" → "desiredSize": "100MB"

Percentage errors: "desiredSize": "0%" → "desiredSize": "25%"

Valid examples

Absolute sizes:

• "desiredSize": "500MB"
• "desiredSize": "2GB"

Percentage-based:

• "desiredSize": "25%"
• "desiredSize": "50%"
