Everything before is normal
Any idea?

It looks like a problem with the discourse-signatures plugin.

Someone is trying to cook a post with raw == nil … that is not supported.

So how can I fix that?

I’ll try again disabling the plugin

Disabling the plugin doesn’t fix the problem

So basically you have a null post (no body, no content) on your site, in your database… we don’t support that.

But that’s not possible :confused:
Can I modify the backup and try to find that null post?

9

Ahh it’s a null signature I can fix that, but remove signature plugin for now

Allright
Tomorrow I will rebuild the site without the plugin signatures and see what happens

11

Yes, without signatures plugin the backup can be restored

Could you fix the plugin? :pray:

I committed a fix for the null column … the official repo is https://github.com/discourse/discourse-signatures be sure to update your app.yml.
