Azure AD with flow routing & Blaze in Meteor 2.7.3

Hi,

I upgraded from Meteor 2.2.4 to 2.7.3. Along the way I needed to solve couple of package compatibility errors but finally got my project to build and start without any errors. However I don’t manage to get accounts-base, useraccounts:flow-routing, accounts-ui, accounts-azure-active-directory stack to work. in Meteor 2.2.4 the same account stack runs ok so I assume i have correct useraccount and azure-ad configuration as well as routing in place. Also if I remove authentication altogether everything else in my app works as before Meteor upgrade.
I did try replacing flow-routing packages with flow-routing-extra but it didn’t make any difference.

Can anyone suggest correct AzureAD useraccount setup in Meteor 2.7.3 or advice what am I getting wrong with my current setup?

More details below

Thanks!

Error I get in browser when I click “sign in with AzureAD” button. Expecting Azure login page as a popup window:

I ensure sign in for all routes by routing rule:

FlowRouter.triggers.enter([AccountsTemplates.ensureSignedIn]);

Which errors did you receive during update? Related to accounts packages? They were updated during 2.3 release and there may be a broken compatibility with one of your packages.

Errors were related to mongo-algolia-sync package dependencies which I resolved by forking it as local package and updating dependencies, so I doubt it’s related to account stack, but dunno.
Would be nice to have some example app which uses accounts-azure-active-directory, Blaze and flow routing
