error while pulling changes from remote mercurial repo

[Ed Wong]

Hi,

I've moved a mercurial repository from an old Kallithea installation to
a new machine (Kallithea 0.7.0) and things have been going on ok.
(Using Python3.9 and mercurial 6.1.4)

Realized I hadn't updated two of the mercurial repositories, so I went
and did a "Pull changes from Remote Repository",  but I
get an error message "An error occurred during pull from remote location".

Fwiw, the two repositories are:
    - https://hg.mozilla.org/comm-central
    - https://hg.mozilla.org/mozilla-central

I took a look at the httpd log, and I came across the following:

Thinking that this might have been some compatibility issue between
the old Kallithea managed repos and the 0.7.0, I thought I'd create
a new repository.

So I went and created another mercurial repo using the same remote
repository (either one): but again, I get an error:

ERROR [kallithea.controllers.admin.repos] Traceback (most recent call last):
   File "/repos/kallithea/kallithea/controllers/admin/repos.py", line

   File "/repos/kallithea/kallithea/model/repo.py", line 407, in create
     return create_repo(form_data, cur_user)
   File "/repos/kallithea/kallithea/lib/celerylib/__init__.py", line 61,

line 776, in send_task
     """
 TypeError: as_task_v2() got an unexpected keyword argument 'ignore_result'


At this point, I'm kinda stuck.   I have Celery == 5.0.5.

Might anyone have any idea of what I'm doing wrong or what
the fix could be?

Thanks
