[HELP] 'TBGatewayService' object has no attribute 'connectors_configs'

[nguyenlam185]

Hi guys, I am currently working with Thingsboard IoT Gateway and trying to get the RPC remote shell to work. The Thingsboard IoT Gateway has been installed on a Raspberry Pi4 which's running on Ubuntu Server 20.04. My tb_gateway.yaml looks like below:

  host: 192.168.0.162
  port: 1883
  remoteShell: true
  remoteConfiguration: false
  statsSendPeriodInSeconds: 3600
  checkConnectorsConfigurationInSeconds: 60
  security:
    accessToken: .....
  qos: 1
storage:
  type: file
  data_folder_path: ./data/
  max_file_count: 10
  max_read_records_count: 10
  max_records_per_file: 10000
connectors:
  -
    name: MQTT Broker Connector
    type: mqtt
    configuration: mqtt.json

I think the Gateway is able to connect to Thingsboard Server whichis hosted on another computer as the server attributes active value is true Now, when I tried to setup the RPC Remote shell, it seems like it failed. It cannot get the OS information, and when I try to enter some commands, the things I got is a message about connectors_configs

Welcome to ThingsBoard RPC remote shell.
Current target device for RPC terminal: TB_Gateway
Remote platform info:
OS: undefined
TB_Gateway> ls
'TBGatewayService' object has no attribute 'connectors_configs'
TB_Gateway> 

Below is the lines I got when I check the status of thingsboard service

ubuntu@ubuntu:~$ systemctl status thingsboard-gateway

Thanks in advance for any suggestion to help me out of this situation.

Hi @nguyenlam185 ,

Please try to use the version from the master branch.

Hi @zbeacon , Thanks for your reply. I followed strictly the installation guide from this link https://thingsboard.io/docs/iot-gateway/install/deb-installation/ So, I don't know the packages is on which branch, also I have not found any instruction on installing the software from git repository. Could you please brief me how to install the version from master branch? Thank you for your support

Hi @zbeacon, Just want to let you know that rolling back to the version 2.6 worked well now. However, I always want to try to lasted version, so I would appreciate if you could help me out of the issue of v2.7

Best regards

Hi @nguyenlam185, if you want to install IoT Gateway from the master branch, you have to:

1. clone the repository from the master branch
2. cd thingsboard-gateway
3. create virtual environment python3 -m venv venv
4. activate the virtual environment source venv/bin/activate
5. python setup.py install
6. and finally run the Gateway python thingsboard-gateway/tb-gateway.py

However, I installed the gateway (following the guideline from the documentation) on a fresh installed Ubuntu Raspberry worked well. Maybe it conflicted with something on my Raspberry at the beginning. So, I think we can close this ticket

Thank you for your support
