System.InvalidOperationException: IDX20803: Unable to obtain configuration from: 'System.String'

Help
1

For some reason I get the following exception when my application is deployed:

System.InvalidOperationException: IDX20803: Unable to obtain configuration from: ‘System.String’.

However, running locally is fine. Having looking into the issue I have tried to verify my Authority is correctly set and so far as I can tell it is.

Application is a .Net 5 Angular SPA

Additionally tried checking the logs on the Auth0 side and I am not seeing any errors. Would anyone be able to provide some further insight into the issue?

Below is the stack trace I get:

Hey there!

In order to solve that most effectively it will be best if you can raise that as a GitHub issue in the SDK repo that you are using so we can address that together with the SDK maintainers directly. Once you have a link to it you can share it here so we can ping them. Thank you!

Hi!

Appreciate the quick response, however I am not using any specific SDK? I am attempting to follow both the Angular quickstarts and the .NET WebAPI quickstarts.

While the front end portion works fine both locally and deployed, the back end controllers seem to fail when I use an attribute like the following:


        [HttpGet]
        [Authorize(Policy = "Moderator")]
        public bool HasModeratorPermission()
        {
            return true;
        }

Any further suggestions on this? Have not been able to replicate locally, this only happens when I have deployed my application.

So far as I can tell this is either a configuration mistake on my end or a bug on the Auth0 end, again any help would be appreciated.

I am getting exactly the same error.

6

Hmm interesting, are you also working with a .NET project?

7

Yes. I am trying to use Auth0 with asp.net web api.

8

Does yours always work locally as well? Seemingly this appears to be something with either Web-API or Auth0 and it seems like Auth0 is refusing my connection from some reason.

Do you have any logging you can add to this thread?

9

It doesn’t work locally for me.

10

No log item on the auth0 side at all

Log on the asp.net core side:

Found the problem. The Authority property was set incorrectly.

        services.AddAuthentication(options =>
        {
            options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
            options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
        }).AddJwtBearer(options =>
        {
            options.Authority = "Auth0 domain"; // this was in correct
            options.Audience = ....
        });

Copied code from two different samples and mixed up the key for the authority.

Bad error message.

Exact same solution here, meant to post it earlier! Thanks for the info though!
