Problems reading in SIRI data

[mirkog]

Hi,

I am trying to read in SIRI data for Norway as described here: http://docs.opentripplanner.org/en/latest/Netex-Norway/

I use `otp-2.1.0-shaded.jar` and have built the graph.obj from the `norway-latest.osm.pbf` file.
Now I am trying to access SIRI data from https://api.entur.io/realtime/v1/rest/et and  https://api.entur.io/realtime/v1/rest/sx (listed by Entur here: https://developer.entur.org/pages-real-time-api). For that I created the following `router-config.json` file:

```
{
    "updaters": [
        {
            "type": "siri-sx-updater",
            "frequencySec": 60,
            "url": "https://api.entur.io/realtime/v1/rest/",
            "feedId": "sx",
            "blockReadinessUntilInitialized": true
        },
        {
            "type": "siri-et-updater",
            "frequencySec": 20,
            "previewIntervalMinutes": 180,
            "url": "https://api.entur.io/realtime/v1/rest/",
            "feedId": "et",
            "blockReadinessUntilInitialized": true
        }
    ]
}
```
When running `java -Xmx6G -jar otp-2.1.0-shaded.jar --load otp_config_folder` I get the following errors:

```

```

What am I doing wrong? I have also tried to add the `sx` and `et` parameters to the URL (since I am not entirely sure what the `feederId` is), but with the same result.

Thanks and kind regards
