# Operation not available in this version

This operation does not exist in the requested version or only in the preview channel (header Bodo-Preview: true).

**Status 404** · `OPERATION_NOT_IN_VERSION`

## Typical cause

The operation does not exist in your version, or it is still in the preview channel and the header `Bodo-Preview: true` is missing.

## Way out

Send `Bodo-Preview: true` for preview operations, otherwise move to the version that has the operation.
