"The specified digest type is invalid" when setting DataDigest and HeaderDigest

[mrdc]

Hello,

I'm using iSCSIinitiator 1.0.0-beta6 on macOS 10.13.6. When I try to set DataDigest and HeaderDigest I get the error

The specified digest type is invalid

Both commands don't work in my case:

iscsictl modify target-config iqn.2000-01.xxxxx.xxxxxx -HeaderDigest CRC32C
iscsictl: No valid options have been specified.

iscsictl modify target-config iqn.2000-01.xxxxx.xxxxxx -DataDigest CRC32C
iscsictl: The specified digest type is invalid

iscsictl list target-config iqn.2000-01.xxxxx.xxxxxx
iqn.2000-01.xxxxx.xxxxxx <inactive, static>
	node-alias:
	auto-login: disabled
	persistent: yes
	Configuration:
		MaxConnections (1)
		ErrorRecoveryLevel (0)
		HeaderDigest (none)
		DataDigest (none)
	Authentication: CHAP
		CHAP-name XXXXXXXX
		CHAP-secret <specified>
	xxx.xxx.xxx.xxx <inactive, port 3260, interface default>

Have tried manually edit the config plist - no luck. With HeaderDigest&DataDigest set to off on a server I'm able to login. CRC32C, crc32c make no difference.
From Wiki:

$ iscsictl modify target-config -HeaderDigest
Supported digest values are none or crc32c. The data digest may be similarly set using:
$ iscsictl modify target-config -DataDigest

Similar issue #98 .

Any ideas how to fix the issue?
