Installing UIBuilder Sets SMTP Port to 0

[jho-md]

Describe the bug
Upon installation of the UIBuilder to a brand new 15.1.2 project with SMTP credentials configured in appsettings.json, SMTP functionality fails to work. Inviting a user to the backoffice produces a fatal server error. After creating a basic logging service that grabs the SMTP Port from the GlobalSettings object, It appears the port is being overridden and set to 0, as show in the screenshot below.

Steps To Reproduce
Steps to reproduce the behavior:

1. Install a new Umbraco Project.
2. Add valid SMTP credentials to appsettings.json under Umbraco:CMS:Global.
3. Install Umbraco UI Builder.
4. Log into the backoffice and go to the users tab.
5. Send an invite to join the backoffice.
6. See that the screen freezes on "Send Invite" then produces a fatal server error.

Expected behavior
The invite email goes through to the user without any errors.

Screenshots

Environment (please complete the following information):

• Server OS: Windows 11, Local Machine
• Umbraco 15.2.1
  -Umbraco UI Builder 15.0.3

Additional context
I've been able to work around this by manually setting the port to 587.

public void Configure(GlobalSettings options) {

    if (options.Smtp == null) {
        return;
    }

    options.Smtp.Port = 587;
}

Hi @jho-md ,

Could you add a little bit more context and details on your setup? I have tried replicating the issue with a local website, as well as a Cloud one and did not experience this.

It is pretty strange though because UI Builder does not interact with SMTP settings at all.

Hope to hear more from you.

@acoumb Here is my code for the SMTPLoggerService.

`using Microsoft.Extensions.Options;
using Umbraco.Cms.Core.Configuration.Models;

namespace MyProject.Smtp;

public class SmtpLoggerService : IHostedService {
private readonly ILogger _logger;
private readonly GlobalSettings _globalSettings;

public SmtpLoggerService(ILogger<SmtpLoggerService> logger, IOptions<GlobalSettings> globalSettings) {
    _logger = logger;
    _globalSettings = globalSettings?.Value ?? throw new ArgumentNullException(nameof(globalSettings));
}

public Task StartAsync(CancellationToken cancellationToken) {
    LogSmtpPort();
    return Task.CompletedTask;
}

public Task StopAsync(CancellationToken cancellationToken) => Task.CompletedTask;

private void LogSmtpPort() {
    var smtpPort = _globalSettings.Smtp.Port.ToString();
    if (string.IsNullOrEmpty(smtpPort)) {
        _logger.LogWarning("No SMTP port configuration found in Umbraco settings.");
    } else {
        _logger.LogInformation($"SMTP is configured to use port: {smtpPort}");
    }
}

}`

I register this in program.cs via builder.Services.AddHostedService<SmtpLoggerService>();

I have just tried again with an Umbraco 15.2.1 project and Umbraco UI Builder 15.1.1 and I am still getting the log that the SMTP port is being set to 0. If I uninstall UI Builder and run the project I get a log message with the correct SMTP port configured in appsettings.

@jho-md could you share the UI Builder collection configuration as well?

[jho-md]

@acoumb I did not configure a collection. I am noticing this issue when the package is first installed.

@jho-md I could not replicate this in any use case, any chance I could get a copy of the source code? thanks
