Fehler Import shapefile aus ArcGIS

Hallo liebe UAV-Editoren,
ich habe versucht ein shapefile aus ArcGIS zu importieren. Koordinaten sind ETRS_1989_UTM. Das shapefile ist ein Polygon, in dem ich einen 200m-Puffer um mehrere Punktkoordinaten gemacht habe (sprich mehrere Kreise mit 400m Durchmesser).
Ergebnis war folgende Fehlermeldung:
{"errors":["ERROR 4: Unable to open /tmp/1ZmovZ3guMlhmJL5op4PSCpu.shx or /tmp/1ZmovZ3guMlhmJL5op4PSCpu.SHX.

Wisst ihr, woran das liegt?
