Tried to do an upgrade through the web UI, it failed. I then did the usual cd /var/discourse git pull ./launcher rebuild app but it also failed (discourse-upgrade-failed.txt): ** FAILED TO BOOTSTRAP ** please scroll up and look for earlier error messages, there may be more than one I’ve found this error, scrolling up. NoMethodError: undefined method `attributes’ for TopicListItemSerializer:Class Now my website is down and I’m really clueless. My question: How to approach this and bring my website back online again?

I’ve fixed this issue in the tagging plugin and it’s now compatible with our stable/beta branches again without failing: https://github.com/discourse/discourse-tagging/commit/04513d372c386a741aa63c3bca7db90784dabb40 @sam we should discuss why I think the extend APIs I baked in there are a good idea – it would have prevented this issue for example.

I’m curious, do you have the discourse-tagging plugin installed? Can you scroll up in the output and see if you spot any other errors? Like this one: [image] NoMethodError: undefined method ‘attributes’ for TopicListItemSerializer:Class

Yes, the discourse-tagging plugin is installed. I’ve attached the whole output and found: NoMethodError: undefined method `attributes’ for TopicListItemSerializer:Class

Yeah you’re getting the same error I am. The latest changes to the tagging plugin seem to have broken my instance. I have temporarily disabled the tagging plugin and was able to build successfully.

Thanks. My post seems to be a duplicate of your post https://meta.discourse.org/t/the-official-discourse-tags-plugin-discourse-tagging/26482/104?u=uwe_keim
