Internal Server Error: /api/organisations/13/
Traceback (most recent call last):

    return Database.Cursor.execute(self, query, params)
sqlite3.IntegrityError: UNIQUE constraint failed: data_manager_organisation_org_actions.organisation_id, data_manager_organisation_org_actions.actiongroup_id

The above exception was the direct cause of the following exception:

Not too sure what makes it happen.. It happened across multiples NGO pages, and on the same page i was able, some times, to link it, others not.

I feel like it's linked to loading --> If all the resources have loaded then i can edit, if they're still loading then i get the error but really not sure at all

Have you ever experienced this by any chance @alexandre @sylvain or @matthieu ?
