Getting the exact same error, started about a week ago

i am receiving the same issue

I'm thinking maybe Dell is working on this because my error changed to:

: Date: 20181114095535

If anyone at Dell could confirm, I'd greatly appreciate it!

All - 

I have a case open with the REC team, which was moved to the Enterprise team. I'm just waiting for a reply back. It does appear to be a Dell issue with the API from what we can see on our side. 

EDIT: Quick update for anyone interested. Here is the reply from my tech: 

I’ll be available at noon .  Yes, as I’m understanding so far this is needing an API fix on our end and already being addressed.  I’m working on getting your case to the right escalation team but just use me as point-of-contact until I get an engineer assigned.

RESOLVED: 

I received good news from my support technician!!! They fixed the back-end issue! I ran a test and it appears to be working as intended now. For anyone else actively watching this thread. Please test and report back on your findings too!

Good morning Travis,

                The Engineer indicated that they resolved the issue this morning.  Can you give it a try and let us know?

this appears to be trying to run but i am receiving this log, mind you have just tried setting this up recently so it may be the syntax 

DellWarranty-CLI.exe /Ics="Data Source=x.x.x.x;Database=cm_xxx;Integrated Security=true;" /E="C:\temp\dellwarranty.csv"

We've got the same issue, does anyone from Tech Support check these forums or do we need to log a fault? : Date: 20181127050055
