It seems that this specific entry DSREGCMD doesn't have the CurrVal\default structure secretsdump is expecting :

reg query HKEY_LOCAL_MACHINE\SECURITY\Policy\Secrets\DSREGCMD
PS C:\Windows\system32> reg query HKEY_LOCAL_MACHINE\SECURITY\Policy\Secrets\DSREGCMD

HKEY_LOCAL_MACHINE\SECURITY\Policy\Secrets\DSREGCMD
    MutexName    REG_SZ    9d0[***]7ce9f
