metricbeat error importing Kibana dashboard

I'm trying to run geonetwork version 4.4.5 via docker compose.

I'm following the instructions in the README.md.

First I run:
docker compose up -d

In kibana I create a new space called catalogue-monitor

then I run:
docker compose -f docker-compose.yml -f docker-compose.monitoring.yml up --build -d

By looking at the logs in the metricbeat container I find the following error:

```

I also tried to run an older version (4.4.2) and I get a similar error.

any help would be appreciated.
