Cannot parse an empty message

[CThomas87]

I'm unsure if it's a bug or user error but I'm trying to retrieve unseen messages, read their subject, post them to discord and mark them as seen in a laravel console command.

Everything seems to be working but when I try to retrieve the subject I get "Cannot parse an empty message".

  public function handle()
    {
        $mailbox = new Mailbox([
            'port' => 993,
            'username' => '',
            'password' => '',
            'encryption' => 'ssl',
            'host' => 'imap.gmail.com',
        ]);

        $discordWebhook = '';

        $mailbox->connect();

        if ($mailbox->connected()) {
            $inbox = $mailbox->folders()->find('Inbox');

            $messageSubjects = [];

            try {
                $messages = $inbox->messages()->withoutFlags('\Seen')->get();

                foreach ($messages as $message) {
                    try {
                        $subject = $message->subject() ?? 'No Subject';

                        $this->info("Found email: $subject");
                        $messageSubjects[] = $subject;

                        // Mark message as seen
                        $message->markSeen();
                    } catch (\Exception $e) {
                        $this->warn("Error processing message: " . $e->getMessage());
                    }
                }

                $this->info('Connected to mailbox successfully.');

                if (count($messageSubjects) > 0) {
                    $this->table(['Email Subjects'], array_map(function($subject) {
                        return [$subject];
                    }, $messageSubjects));

                    $this->postToDiscord($discordWebhook, $messageSubjects);
                } else {
                    $this->info('No unread emails found.');
                    $this->postToDiscord($discordWebhook, [], false, true);
                }
            } catch (\Exception $e) {
                $this->error('Error retrieving messages: ' . $e->getMessage());
                $this->postToDiscord($discordWebhook, [], true, false, $e->getMessage());
            }

            return 0;
        }

        $this->error('Failed to connect to mailbox.');

        $this->postToDiscord($discordWebhook, [], true);

        return 1;
    }
