Answer 1

Your issue is com.tridion.smarttarget.promotions.Promotion.updateMetaDataPromotion(Promotion.java:564)

Metadata promotion is the promotion containing metadata on all promotion. If you cannot update it, then you need to check if indexer on fredhopper is working, if it is available, and if you can update promotions over it. So please restart indexer first, verify it is available, and then check if it possible again.

As an update, it seems like your metadata promotion is DELETED since it returns 404.

Answer 2

Normally if the Meta Promotion is gone, it will just be recreated (albeit with some data loss). So I don't think the problem is that it has been deleted.

It seems more like a configuration issue to me. Either the URL to Fredhopper is wrong, or the credentials used are invalid. That might also result in a 404 error. The Fredhopper logs should tell you what is going on.

You can also try to log into the Business Manager using the details in the configuration; that might bring the issue to light.
