Error while trying to edit a post or change ownership of it


(Miguel Hurtado) #1

Hi I’m having troubles in my installation of Discourse (v1.6.0.beta8 +28) after upgrading it today.

When trying to edit some posts I receive an error: 422 Unprocessable Entity. I notice that if I modify the title and the content only the title gets updated. The error mentioned is always thrown. This behavior doesn’t occur with all posts and new posts are not affected by this.

On the logs this shows up:

When I try to change ownership of a post both errors are thrown as well. This is more consistent and happens with all post.

Let me know if you need more information.

Is it a duplicate title? Duplicate topic titles are not allowed out of box.


(Miguel Hurtado) #3

No, no other post has the same title.


(Alan Tan) #4

I’ll have a look at this today. This is happening because we are now raising an error instead of silently ignoring it in the past when topic links fail to be created.


Tag changes persist throughout entire edit history
(Steve Combs) #5

I had the same issue today on a wiki post in a private category. Could not edit the text. 422 error. Log indicated duplicate URL.

Opps my bad… Fixed in


(Miguel Hurtado) #7

I can confirm this fixed the issue in my installation. Thanks guys! :grinning:
