RANGE_MISSING_UNIT

The RANGE_MISSING_UNIT error occurs when the unit identifier of the Range header in a request is missing. The Range header is used to request a specific portion of a resource from the server, and the unit identifier indicates the unit in which the range is specified, such as bytes.

To troubleshoot this error, follow these steps:

1. Specify unit identifier: Ensure that the Range header in your request specifies a unit identifier like bytes
2. Check configuration: If the Range header values are being set automatically by some part of your system, check the configuration to ensure the unit identifier is being included
3. Verify syntax: Verify that the syntax of the Range header is correct and follows the format unit=range-start-range-end, for example, bytes=0-999
4. Debugging: If the error persists, log the Range header values in your server logs to debug and understand what values are being sent in requests
