Campaign-tasks don't start (& campaign stuck in loop) - bug (5.1.0)

Your problem

I have 2 campaigns:

1. Camp. “REAKT6-01”: When I add contacts to this campaign [via adding them to the segment “REAKT-01”], following things should happen:

So:
– Getting the tag “Started campaign: REAKT6-01” (this works)
– Sending email #135 (also works)
– 2 days later adding contact to campaign “MASTER”:

This does NOT work, instead he gets added every 15 minutes to that MASTER-campaign (based on the contact’s History), but that MASTER-campaign does still not start

– Stopping this “REAKT6-01” campaign (this does NOT work, it’s not reached, as the flow stucks at the previous step

2. Camp. “MASTER”: This has as starter the empty segment “NOBODY”, as I want to start it just via other campaigns (like campaign “REAKT6-01”).

The contact’s “Upcoming Events” shows following (the date “July 30, 2024 8:18 pm CEST” is of course already over, but for many contacts it still tries to add it to the MASTER-campaign every 15 minutes, already 25+ times):

And checking the contact’s Campaigns, that MASTER campaign IS active:

Please help me solving this, so the contacts come out of that loop and the MASTER-campaign finally starts.

These errors are showing in the log:
Nothing, is empty

Steps I have tried to fix the problem:

• I tried changing the MASTER-Campaigns starting-segment from “NOBODY” to a newly created segment called “Start Master campaign”, but even adding a contact to this segment did not actually start the MASTER-campaign.
• I created a totally new contact and activated the MASTER-campaign for it, but still it didn’t fire
• I cloned that MASTER-campaign as test and when I added a test-contact to it, that clone-campaign fired correctly. However just cloning and replacing the original with this clone can’t really be a solution, as (as I just realized) other campaigns have also this issue (that despite being added to them, their flow doesn’t start)

Hi,
What is starting the Master camapign? Segment membership?
I understand now you want to add the contact to the campaign directly, but normally would it be segment membership or form fill out?

[imihandstand]

I never use the form fill out for starting campaigns.
The MASTER campaign has set up as starter the segment “NOBODY” (which is an empty segment), to just start via the 1st campaign (REAKT6-01).

But the way it’s started can’t be the issue, because:

• When I start the campaign for a contact via activating it manually on his profile, the campaign still doesn’t start the flow
• When I clone the campaign (without changing anything), the clone works as intended
