(Juniper) - KeyError (CMS) cause by a jwkest.BadSignature error

[BbrSofiane]

I've installed and added the eoc-journal xblock on a native installation of juniper but when I insert the component into a course, I get the following errors in LMS and CMS.

Is the current version of the block compatible with Juniper?

@BbrSofiane, Thanks for reporting the issue. This xblock is only known to work till Ginkgo. We are yet to find out its compatibility with Juniper and later releases.
