Cannot Disable Asynchonous Audit Logging - Error

Version 1.12.0

I tried to set:

opendistro_security.audit.threadpool.size: 0

And I get:

[2021-02-23T15:04:03,461][WARN ][c.a.o.s.s.ReflectionHelper] [opendistro-es-client-7d667cbb96-5lg7m] Unable to enable Auditlog Module due to java.lang.IllegalArgumentException: Incorrect thread pool size: 0 configured for audit logging.
