JsonParsingException at GeoJSONReader.parse

[anonymous]

What steps will reproduce the problem?

1. Geojson-Dateien, welche ich aus Opendataportalen geladen habe, lassen sich zwar in JOSM für macOS öffnen, aber es wird nichts dargestellt

What is the expected result?

What happens instead?

Please provide any additional information below. Attach a screenshot if possible.
