FCCS Migration Failed EPMFCM-30008

Hi,

I'm migrating FCCS prod environment to test environment and there's one schedule that gives an error:

/Close Tasks/Schedules/2024 09 NF IFRS S2 :- EPMFCM-30008: Invalid LCM import ZIP file. Make sure the LCM import file is in the correct format; for example, a number attribute has a number format value.;

I see that the schedule is created and the tasks inside it too, but the actions inside the tasks aren't there.

I've already checked all the attributes in the tasks and there's no problems, but when I enter one of the tasks in the Questions section, the information and the attachments aren't there, so I assume the problem is with the file attachments, but I don't know how to resolve the issue.
