Move the configuration option torrent_info_update_interval:
[database]
connect_url = "sqlite://storage/database/torrust_index_backend_e2e_testing.db?mode=rwc"
torrent_info_update_interval = 3600
from the [database] section to a new section [tracker_statistics_importer], like this:
[database]
connect_url = "sqlite://storage/database/torrust_index_backend_e2e_testing.db?mode=rwc"
[tracker_statistics_importer]
torrent_info_update_interval = 3600
as discussed here.
