Grafana not receiving any data to display

[dpliatsios]

Hello, I encounter an issue with Grafana, showing "No data" and "An error encountered with the plugin", as shown in the screenshot below:

Moreover, the following error is shown when starting Grafana through the docker compose:

The relevant section in the config.yml is as follows:

remote_control:
    bind_addr: 0.0.0.0
    enabled: true
    
metrics:
  autostart_stdout_metrics: true
  enable_json: true
  layers:
    enable_app_usage: true
    enable_mac: true
    enable_app_usage: true      # Enable application usage metrics
    enable_e1ap: true           # Enable E1AP metrics
    enable_pdcp: true           # Enable PDCP metrics
    enable_sched: true          # Enable DU scheduler metrics
    enable_rlc: true            # Enable RLC metrics
    enable_mac: true            # Enable MAC metrics
    enable_executor: true       # Enable DU-high executor metrics
    enable_du_low: true         # Enable DU low metrics (upper physical layer)
    enable_ru: true             # Enable Radio Unit metrics
  periodicity:
    app_usage_report_period: 10000
    cu_cp_report_period: 1000
    cu_up_report_period: 1000
    du_report_period: 1000      

Finally, note that if I run the commend: WS_URL="127.0.0.1:8001" ./ws_adapter.py, I can see the metrics being printed in the terminal.

If additional configuration files or information are needed, please let me know.
