Cannot Email Report On Demand

[d1m17ar]

When trying to mail a report instantly


we're getting the following error:

[2026-09-16 06:32:20] DEBUG: API (403) Cannot link an already linked attachment (Email:attachments).; POST /Email; Route pattern: /{controller}; Route params: Array ( [controller] => Email [action] => create )
[2026-09-16 06:32:20] NOTICE: (403) Cannot link an already linked attachment (Email:attachments). :: POST /Email
[object] (Espo\Core\Exceptions\ForbiddenSilent(code: 403): Cannot link an already linked attachment (Email:attachments). at /var/www/html/application/Espo/Core/Exceptions/Forbidden.php:62)

I tracked it to Espo\Modules\Advanced\Tools\Report\SendingService. php

if ($attachmentId) {
    $data->attachmentId = $attachmentId;

    $attachment = $this->entityManager->getEntityById(Attachment::ENTITY_TYPE, $attachmentId);

    if ($attachment) {
        $attachment->set([
            'role' => 'Attachment',
            'parentType' => Email::ENTITY_TYPE,
            'relatedId' => $id,
            'relatedType' => ReportEntity::ENTITY_TYPE,   // <-- this is the problem
        ]);

        $this->entityManager->saveEntity($attachment);
    }
}​ 

Could you please take a look. Thanks.
