We have this custom activity in my Journey and we do a validation of these contacts on our side. If the contact validation failed on the custom activity journey, we want it to stop the journey of that specific contact but still continue with the other contacts.
The scenario is like when you add an outArguments in your config.json but you did not provide it on the response from the server. But we do not want to put an outArguments.
We've tried to return 400 and 500 but still the contact has a Success status instead of Hard Error. We want to put it on a Hard Error or Soft Error status instead of Success status for that specific contact. How can we do that?
