If you’re using a Decoder in TTN Console, then beware that the Data Storage Integration [silently fails for attributes with `null` values](https://www.thethingsnetwork.org/forum/t/data-storage-not-showing-decoded-data-and-only-stores-data-two-times-a-day/39316/9). > [@mattb1969](#): > > ?last=7d Indeed, that may surely help. The default is 1 hour. Asides: note that a non-existing device ID will return 204 No Content too (if it does adhere to the naming rules). And note that the integration will store at most 7 days of data. There may also be some [limit for the maximum number of results](https://www.thethingsnetwork.org/forum/t/is-there-any-limit-in-the-number-of-results-when-querying-the-data-storage-integration/35430), but one should not run into that when adhering to the Fair Access Policy. --- _[View the full topic](https://www.thethingsnetwork.org/forum/t/data-storage-device-id-query-not-working/40516)._
