What is the workaround for HIUtil 2 output being incompatible with High Sierra?

We shifted our build environment to Mojave and now our help books are incompatible with High Sierra.
This is very inconvenient.
What is the workaround?

We're copying an old hiutil to the build machine under a different name and then building both indices to include in the release. This appears to work on our target OS set without bad side effects since the indices are named differently.

Have you checked thet HiUtil version is on par with your version of XCode ?
