**Your software** My Mautic version is: v2.16.2 My PHP version is: v7.3.14 **Your problem** My problem is: I have a PDF asset that users can request by filling in a form (Gravity Forms → Zapier → Mautic), which works. I send the asset download link by mail to the user from within Mautic. The following happens: - The asset downloads correctly - Mautic shows the contact has opened the mail, but not that they have downloaded the asset. - The asset\_downloads table is empty - The asset page does show the correct number of downloads - The user doesn’t get added to a segment of users who have downloaded that asset These errors are showing in the log: none - in fact, there’s no entry at all in the logs. The Apache log shows the asset being downloaded. Steps I have tried to fix the problem: - I’ve checked that the link in the email is encoded by Mautic (it is). - I’ve ensured that the user receiving the email is not logged into Mautic (they don’t have a Mautic account, but I logged out anyway) - I tried to follow the code page but got lost at index.php(!). If someone can point me to where in the codebase to look, I’ll try some debugging. ---

I’ve found an error in the Apache log. This error is repeated every time the asset is downloaded. Can anyone shed any light on this? `[Wed Jun 24 20:19:58.144496 2020] [proxy_fcgi:error] [pid 27810:tid 140140244576000] [client 2001:678:32c:57af::1005:59668] AH01071: Got error 'PHP message: Doctrine\\ORM\\ORMInvalidArgumentException: A new entity was found through the relationship 'Mautic\\AssetBundle\\Entity\\Download#lead' that was not configured to cascade persist operations for entity: Mautic\\LeadBundle\\Entity\\Lead with ID #.

How can I move this forwards? Either I misunderstand what Mautic should be able to do, or there’s a configuration problem or there’s a bug. If someone would point to where in the code asset tracking is implemented, I’ll try to dig deeper. Thanks. ---

I’ve now set up a virgin 2.16.2 installation to try this. The good news is that I don’t get any errors anywhere. The bad news is that it still doesn’t work. Really looking for a way to move this forwards. What can I do to help?
