Description

I am using the 2-1-CallMSGraph sample, but I am getting errors about redirects.
As a prerequisite, local sign-in worked fine.
This time, we are planning to configure the app to redirect and access https:.azurewebsites.net/xxx/signin-oidc to sign in and get Azure AD information.
Therefore, we have made the following changes to the AzureAd property in the appsetting.json file.

"AzureAd": {
    "Instance": "https://login.microsoftonline.com/",.
    "Domain": "<MyDomain>",.
    "ClientId": "<MyCrientId>", { "ClientId".
    
    "RedirectUri": "https://<MyAppName>.azurewebsites.net/xxx/signin-oidc", "RedirectUri". 
    "ClientCertificates": [
    ],.
    // the following is required to handle Continuous Access Evaluation challenges
    "ClientCapabilities": [ "cp1" ], "CallbackPath": [ ], //the following is required to handle Continuous Access Evaluation challenges
    //"CallbackPath": ""
  }, }
"DownstreamApi": {
    "BaseUrl": "https://graph.microsoft.com/v1.0", }, "DownstreamApi": {
    "Scopes": "user.read"
  }
  

Also, for Azure app authentication settings, as a redirect URI,
https:.azurewebsites.net/xxx/signin-oidc is registered.

Assuming the above, we deployed to Azure Web Apps. However, when I access the app, I get the following error
Error AADSTS50011 - The redirect URI "https:.azurewebsites.net/signin-oidc" specified in the request does not match the redirect URIs Make sure the redirect URI was sent.
Make sure the redirect URI sent in the request matches one added to your application in the Azure portal.
Navigate to https://aka.ms/redirectUriMismatchError to learn more about how to fix this.

Despite changing the redirect URI setting, the URI does not seem to match, as it is coming from https:.azurewebsites.net/signin-oidc.

https://learn.microsoft.com/ja-jp/troubleshoot/azure/active-directory/error-code-aadsts50011-redirect-uri-mismatch
I referred to the above and it says to set the redirect URI in Azure App Authentication, but I don't know why as I have already registered it.

Where in the source code or in the configuration file should I change the URI to https:.azurewebsites.net/xxx/signin-oidc instead of https:.azurewebsites.net/signin-oidc? in the source code or in the configuration file?

@YHgitaccount :

1. Don't change the redirect URI in the appsettings.json. The app knows already
2. did you read this article?

Thanks for your response.

Regarding 1,
In the "Update the redirect URLs" section of the reference link you commented on, there is the following statement: 5.
5. "If your application calls a web api, make sure to apply the necessary changes on the project appsettings.json, so it calls the published API URL instead of localhost."
I am aware that I need to change the URL to include the domain name of the Web Apps, is that correct?

Also, follow the "Update the redirect URLs" section of the same link,
Add "https://.azurewebsites.net" to the Redirect URL for the Azre AD app,

I registered the following two

• https://.azurewebsites.net
• https://.azurewebsites.net/xxx/signin-oidc

However, the situation did not change, so I checked the stack and races in developer mode and received the following error

Where else would be appropriate to check?
We would appreciate your comments as we are very troubled.

Here, I solved the problem by changing the root path in the application settings.
