Encountering a 500 Internal Server Error while making a call to a RESTful (GET) Web

Currently, I have a setup where my web server is housed inside a virtual machine, with the client located outside of it.

On the server side, I am utilizing .NET Framework 4.6.1 for development.

Below is the architecture of my WEB API controller on the server-side:

// GET: api/Users
    public IQueryable<Users> GetUsers()
    {
        db.Configuration.ProxyCreationEnabled = false;

        return db.Users;
    }

    // GET: api/Users/5
    [ResponseType(typeof(Users))]
    public IHttpActionResult GetUsers(string id)
    {
        db.Configuration.ProxyCreationEnabled = false;
        Users users = db.Users.Find(id);
        if (users == null)
        {
            return NotFound();
        }

        return Ok(users);
    }

When I access http://localhost:50347/api/Users/id from the browser within the virtual machine, IIS express responsds correctly.

On the client side, the request is made like this using TypeScript:

login(account: Account): Observable<Utente> { 
let apiURL = `${URL.LOGIN}/${account.username}`;                                                        
return this.http.get<Utente>(apiURL);                                                                   

Specifically, it calls .

However, when attempting to directly access from the browser, it results in an error message:

This XML file does not appear to have any style information associated with it. The document tree is shown below.

Any assistance on resolving this issue would be greatly appreciated. Thank you in advance.

Answer №1

After some troubleshooting, I managed to find a solution:

I made the following changes:

  1. Switched the connection string from: integrated security=True to user id=user_id;password=your_password.
  2. Changed the IIS from IIS express to IIS local.

As a result, the communication is now functioning properly.

It appears that the issue was related to IIS attempting to connect to the database using Windows user authentication, which was causing permission problems outside of the Windows environment (specifically on macOS). Thank you to everyone for your help.
