Hi experts,

I am using my trial account to run the mission but getting an error whilst deploying the app. The error is as follows:

Detection of HDI version failed; root cause: Connection failed (RTE:[-1] Kerberos error. Major: "unspecified [851968]", minor: "No Kerberos credentials available (default cache: FILE:/tmp/krb5cc_2000) [2529639053/-1765328243]" (10.143.176.143:38116 -> zeus.hana.prod.us-east-1.whitney.dbaas.ondemand.com:21022)) (STDOUT, APP/TASK/deploy)#

I am using the subaccount in US.

Any thoughts?

Thanks!
