Merge users not possible from UI or CLI

Hello community,

Discourse version : 2.9.0.beta9( 42c64abe15 )

After a merger of two successful Discourse communities, there are some duplicate users (especially those who did not put the same addresses)

But unfortunately, the user merge tool integrated in the UI does not work, it runs in a loop without stopping.
So I tried it in CLI, but it also failed.

cd /var/discourse
./launcher enter app

from user root discourse

rake users:merge['olduser','keepuser']

Do you manage to merge users in your instances via the UI? (I point out that they are not moderators or admins)

do you have an idea ?

Thanks for advance

Here are the traces.

root@discoursetest-app:~# rake users:merge['olduser','keepuser'] --trace
** Invoke users:merge (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute users:merge

Hi,

I ran into the exact same issue today. Slightly older version (2.8.3) but same result on the UI and CLI. The old user is no admin, but the new one is.

Would be really great if anybody could shed some light on this.

Thanks


CLI Output:
