  • Steps to reproduce the issue:

I extended the existing IdentityUser with the extension system, and also had it mapped to a different column using ef core mapping, which is working fine locally.

Normal behavior locally when adding or editing a user:

After deploying to Azure, is not working anymore and I get a Blazor error when trying to add or edit a user:

If I go to /api/providers I get a normal response:

What am I doing wrong? Please note that all other aspects of the app deployed to AZ are working as intended.

    Hi ccernat,

    Can you please check your deployed database to see if the values for ProviderId are present or not?

    Hello!

    All good there. As I said, if I access the endpoint /api/providers on Azure, I get the correct response, with the providers list, as shown in the screen in the 1st post.

    hi

    Please add the MyBlazorServerLookupApiRequestService to your blazor project and try again. The error logs will show the reason.

    After the above test, you can add RemoteServices to your appsettins.json

      "RemoteServices": {
        "Default": {
          "BaseUrl": "https://your-real-url-dev.azurewebsites.net/"
        }
      },

    This is because it's returning the login page, but I am logged in and the controller is decorated with the Authorized for Admin role. I wouldn't want to allow anonymous on that endpoint.

    PS: Shouldn't the app settings related to RemoteServices:Default:BaseUrl be generated with the Blazor Server template from ABP Suite?

    hi

    Please add these code to output the headers.

    We have to attach the cookies to call the endpoint.

    If there is no cookies, the HTML of login page will show up.

    // Blazor server mode
    client.BaseAddress = new Uri(NavigationManager.BaseUri);
    foreach (var header in HttpContextAccessor.HttpContext!.Request.Headers)
    {
        Logger.LogInformation("Header: {0} = {1}", header.Key, header.Value);
        requestMessage.Headers.TryAddWithoutValidation(header.Key, header.Value.ToArray());
    }

    hi

    Thank you!

    We have to remove the Accept-Encoding header.

    The solution is:

    
    // Blazor server mode
    client.BaseAddress = new Uri(NavigationManager.BaseUri);
    foreach (var header in HttpContextAccessor.HttpContext!.Request.Headers.Where(x => x.Key != "Accept-Encoding"))
    {
        requestMessage.Headers.TryAddWithoutValidation(header.Key, header.Value.ToArray());
    }

    Hi,

    It's working correctly now but only returns 10 items.

    Where can I change the paging? Or to return me all the items from the controller?

    hi

    You can add a new method to app service to get all items.

    Or set the MaxResultCount of GetProvidersInput to int.MaxValue.

    so add a new method will be better.
