Deduplication error au_915_0

RickH · August 1, 2024, 5:54pm

Hi,

We are working with ChirpStack V4 and a Milesight UG67 (firmware version: 60.0.0.43-r2) gateway. We have configured the chirpstack.toml, region_au915_0.toml and chirpstack-gateway-bridge.toml files according to the ChirpStack documentation for Debian/Ubuntu. While we can see the gateway online in the GUI, the devices added to the application show the following errors:

INFO chirpstack::gateway::backend::mqtt: Message received from gateway region_id="au915_0" topic=gateway/24xxxx/event/up qos=AtMostOnce json=false
WARN chirpstack::uplink: tx_info of uplink event is empty, skipping
ERROR chirpstack::uplink: Deduplication error error=Unable to get first item from rx_info
INFO chirpstack::gateway::backend::mqtt: Message received from gateway region_id="au915_0" topic=gateway/24xxxxx//event/up qos=AtMostOnce json=false
WARN chirpstack::uplink: tx_info of uplink event is empty, skipping
ERROR chirpstack::uplink: Deduplication error error=Unable to get first item from rx_info

We would appreciate any hints on how to resolve the Deduplication error.
@brocaar any idea?

Thanks!

Are you using the latest ChirpStack gateway bridge?
Are the uplink and downlink working?

- [x] The issue is present in the latest release. - [x] I have searched the [issues](https://github.com/brocaar/chirpstack-gateway-bridge) of this repository and believe that this is not a duplicate. ## What happened? I run chirpstack using chirpstack-docker containers and repo. On trying to run latest tag on chirpstack v4.6.0 I get the following errors on the gateway bridge with no data being transmitted. ## What did you expect? Latest to be compatible with v4.6.0 / as this is whats pulled from docker with container tag 4 ## Steps to reproduce this issue Steps: 1. replace gateway bridge from 4 to latest in docker compose ## Could you share your log output?  This is a snippet of one error, as the logs are full of these for every uplink from all gateways on every region. ```shell chirpstack-docker-chirpstack-1 | 2024-01-12T08:28:56.977789Z INFO chirpstack::gateway::backend::mqtt: Message received from gateway region_id="au915_1" topic="au915_1/gateway/2864afc74baa57f1/event/up" qos=0 json=false chirpstack-docker-chirpstack-1 | 2024-01-12T08:28:57.180429Z WARN chirpstack::uplink: tx_info of uplink event is empty, skipping chirpstack-docker-chirpstack-1 | 2024-01-12T08:28:57.180469Z WARN chirpstack::uplink: tx_info of uplink event is empty, skipping chirpstack-docker-chirpstack-1 | 2024-01-12T08:28:57.180702Z ERROR chirpstack::uplink: Deduplication error error=Unable to get first item from rx_info ``` ## Your Environment This is docker-chirpstack running on ubuntu cloud server, built new as version 4 - so not an update from v3.
