I have the same issue, it is related to a migration which is not present in the last versions of open project :

https://github.com/opf/openproject/blob/v10.6.5/db/migrate/10000000000000_to_v710_aggregated_migrations.rb

Is there an issue in the version provided ? We should not see this migration, on the 17.0.1 tag we get a 404 -> https://github.com/opf/openproject/blob/v17.0.1/db/migrate/10000000000000_to_v710_aggregated_migrations.rb

Sorry for the late answer !
I didn't do that previously, thanks !

The documentation forgets to mention it's necessary to set DJANGO_SETTINGS_MODULE=settings.config env to make the load_dump command work !

Hi,
In our company we use an old version on Taiga and want to migrate Taiga to cloudron.
I tried exporting one of the projects we have in our previous installation.
Due to the size of the exported file (1.4Gb) , I had to export it with manage.py command.

I tried to upload the export on a new project but the file size is too big. So I uploaded the file with cloudron's file manager.
I tried then to import the file with manage.py using this command :

python3 manage.py load_dump my_export.json  my_email_address

I got this error :

Traceback (most recent call last):
  File "/app/code/taiga-back/manage.py", line 15, in <module>
    from django.core.management import execute_from_command_line
ModuleNotFoundError: No module named 'django'

I also tried to edit nginx.conf file but it's readonly.

Is there any way to change nginx config or make the manage.py command work ?

Thanks
