I've followed [this tutorial](https://learn.microsoft.com/en-us/aspnet/core/blazor/security/webassembly/hosted-with-azure-active-directory-b2c?view=aspnetcore-5.0) line by line. It's teaches how to generate a blazor wasm hosted application with all the code to authenticate with Azure B2C. All I had to do was to replace place the correct values in the right places.

`dotnet new blazorwasm -au IndividualB2C --aad-b2c-instance "{AAD B2C INSTANCE}" --api-client-id "{SERVER API APP CLIENT ID}" --app-id-uri "{SERVER API APP ID URI}" --client-id "{CLIENT APP CLIENT ID}" --default-scope "{DEFAULT SCOPE}" --domain "{TENANT DOMAIN}" -ho -o {APP NAME} -ssp "{SIGN UP OR SIGN IN POLICY}"`

Unfortunately, when I run it I get this error:

[![enter image description here](https://i.stack.imgur.com/67ipV.png)](https://i.stack.imgur.com/67ipV.png)

It's hard to tell where the problem is coming from. I googled the error but can't find any documentation on the issue.

Thanks for helping.

Edit
====

Here's the script that I use to create the Blazor app

`dotnet new blazorwasm -au IndividualB2C --aad-b2c-instance "testb2c.onmicrosoft.com" --api-client-id "3b113bda-55d5-47eb-9d8c-5e44375f1341" --app-id-uri "https://testb2c.onmicrosoft.com/testapi" --client-id "3b9fd635-a87f-4899-ad04-9a73fc6f4e21" --default-scope "api.read" --domain "testb2c.onmicrosoft.com" -ho -o BlazorCmdLine -ssp "B2C_1_SignUpIn"`
