Can't send Magic link data to next step workflow

Hello,

A few weeks ago I implemented Magic Link on my App through SendGrid dynamic template. It worked fine until recently where the magic link is not being passed to the SendGrid workflow action it seems, resulting in the SendGrid email being sent, but with no clickable link as data is empty as per debugger.

I did not touched anything thus I don’t understand why it suddenly stopped working.

Any help would be greatly appreciated!

Thanks
