RANGE_START_NOT_VALID

The RANGE_START_NOT_VALID error occurs when the start value of the Range header in a request is invalid. The Range header is used to request a specific portion of a resource from the server, and the start value should be a valid integer indicating the beginning of the requested range.

To troubleshoot this error, follow these steps:

1. Validate Range header values: Ensure that the start value in the Range header is a valid integer. It should not be a letter, a decimal, or a scientific notation value
2. Correct ordering: Ensure the start value is less than the end value in the Range header, if an end value is specified
3. Check configuration: If the Range header values are being set automatically by some part of your system, check the configuration to ensure it's being set correctly
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
