Thanks in advance

[FabianGosebrink]

I am not @damienbod but have you tried updating your angular app to V12?

[garvraj]

Ahh Sorry for wrong tag,

No I have not updated to V12, my angular was V12 from start , I just installed angular-auth-oidc-client

[FabianGosebrink]

Ah then please make sure you use this lib in V12 with Angular in V12.

[garvraj]

Ah then please make sure you use this lib in V12 with Angular in V12.

So if I use V11 angular then i must use angular-auth-oidc-client version 11

[FabianGosebrink]

Normally Angular 11 should work with this Lib V12. But you said, that you're on Angular 12, right?

my angular was V12 from start

Not exactly, My issue is because I was using angular 11 with V12 angular-auth-oidc-client

[FabianGosebrink]

Can this be closed then?

[garvraj]

Yes this can be closed but still I did not understand why angular 11 with V12 angular-auth-oidc-client cannot be used

From https://angular.io/guide/creating-libraries#ensuring-library-version-compatibility

The Angular version used to build an application should always be the same or greater than the Angular versions used to build any of its dependent libraries. For example, if you had a library using Angular version 12, the application that depends on that library should use Angular version 12 or later. Angular does not support using an earlier version for the application.
