Auth scheme may not be null

Hi Community,

I am using Orchestrator 7.6 and HTTP-REST plugin 2.3.3.13946087.

From time to time when getting REST session with "/rest/com/vmware/cis/session" against vCenter 6.7U3 I get error message "Auth scheme may not be null".

Does this ring a bell ?

Thanks

Fred

Hi Fred,

I recall there was something similar reported previously when doing multiple requests in parallel.

Any error stack traces (or other clues) in vRO and/or vCenter logs?

It's definitely an issue with the REST plug-in.

My only advice is to build Auth failure retries into your logic. I also heard that using the REST plugin transientHost method helps to alleviate the issue but I can't say whether that's the case as I never refactore after it was introduced.

Hello Guys,

Seems that the issue is related to the number of concurent requests.  Since we decreased we did not see this issue appear again

Thanks a lot for helping Smiley Wink
