Bug Description

I am using the Microsoft App in UVdesk to fetch emails from Office 365. After making some code adjustments, both email reception and sending work as expected.

I have set up a cron job that fetches emails every five minutes. The job was started at 11:10 PM and ran smoothly until 12:30 AM. However, starting from 12:35 AM, I began receiving the following error message:

Retrieving mailbox configuration details for [email protected]:
An unexpected error occurred: Warning: Undefined variable $microsoftApp

Steps to Reproduce

1. Connect the Microsoft App to Office 365 mailboxes.
2. Set up a cron job to fetch emails every 5 minutes.
3. Start the cron job at 11:10 PM.
4. Emails are successfully fetched until 12:30 AM.
5. From 12:35 AM onwards, the error mentioned above occurs.

Expected Behavior

The cron job should continue fetching emails without interruptions or error messages.

Actual Behavior

The cron job triggers an error after running for a certain period, indicating an undefined variable $microsoftApp.

Code Adjustments Made

1. Changes in vendor/uvdesk/core-framework/Controller/MicrosoftApps.php at Line 149:

   $redirectEndpoint = str_replace('http', 'https', $this->generateUrl('uvdesk_member_core_framework_integrations_microsoft_apps_oauth_login', [], UrlGeneratorInterface::ABSOLUTE_URL));
   

   changed to:

   $redirectEndpoint = str_replace('http://', 'https://', $this->generateUrl('uvdesk_member_core_framework_integrations_microsoft_apps_oauth_login', [], UrlGeneratorInterface::ABSOLUTE_URL));
   

   This change was necessary to establish a connection with Microsoft.

2. Changes in config/packages/uvdesk.yaml:

   • The "site_url" was adjusted avoid errors related to the webhook (API) delivery.

3. Changes in vendor/uvdesk/mailbox-component/Console/RefreshMailboxCommand.php:

   • Modified the following lines to ensure the correct URL scheme is used:

   $this->router->getContext()->setHost($this->container->getParameter('uvdesk.site_url'));
   $this->router->getContext()->setScheme('https');
   // $this->router->getContext()->setScheme((bool) $input->getOption('secure') ? 'https' : 'http');
   

   The above change ensures that the emails are properly delivered via HTTPS.

Additional Information

• UVdesk Version: 5.4.42
• PHP Version: 8.1.2
• Webserver: Plesk with Nginx and Apache
• Operating System: Ubuntu 22.04.4 LTS

Possible Solution

The $microsoftApp variable might be getting lost or not correctly initialized after a certain runtime. It could be necessary to review and correct the initialization of this variable.
