Error occurs during configuration of ESR in CE

Question

I'm doing the "Configuration of ESR in CE" senario in the NWA.
In the final step: Importing XI content
following error happened:
Error: Password cannot be null or empty
and I found following exception in log:
importContentInput
<importContentInput>
<!<filePath><expr:Expression message="SystemInfo">concat(concat('/usr/sap',/Profiles/SystemProfile/INSTANCE_NAME/text()),'/SYS/global/xi/exchangeProfile')</expr:Expression></filePath>>
<contentDirPath>D:\usr\sap\CE1\SYS\global/xi/content</contentDirPath>
<!How to determine correct slashes wrt the OS>
<importUrl>http://IDSMYN:50000/rep</importUrl>
<userName>ESRCMSCE1</userName>
<password>% secure content %</password>
</importContentInput>
This user is created when installing the system, shall I reset the password of it? or any other approach?
Thanks,
YiNing

After restarting the whole cluster and resume the configuration, following error infomation has been found:
