Error while importing policy: Could not change assigned objs

Good morning,

I've been in trouble with importing some policy from one of my firewalls.

I have identified the problem: It comes from a global profile group.

I haven't been able to find what "Could not change assigned objs" means in the report. (You can find it in attachement, line 140).

I enabled partial-install on my Fortimanager, and tried to push the group from the Global adom to my Fortigate unit.

I wanted to try to push the object, and then try to import the policy, to see if it would fix the problem.

But It gets stucked at 5%.

I would be really grateful if someone could provide some help, or at least, had an idea about what happens.

Best regards,

Kevin
