geoserver upload kml no format - api

Question

I'm using the API of the geoserver (link) to upload a new kml file to mu local machine using a post request to http://localhost:8080/geoserver/rest/imports with the following json
{
"import": {
"targetWorkspace": {
"workspace": {
"name": "sample"
}
},
"targetStore": {
"dataStore": {
"name": "sample"
}
},
"data": {
"type": "file",
"file": "/data/sample_dir/sample.kml"
}
}
}
I should get the data type and the state as ready on the response according to the API documentation but I'm getting a pending and no file format.
Response:
{
"import": {
"id": 23,
"href": "http://localhost:8080/geoserver/rest/imports/23",
"state": "PENDING",
"archive": false,
"targetWorkspace": {
"workspace": {
"name": "sample"
}
},
"targetStore": {
"dataStore": {
"name": "sample",
"type": "Directory of spatial files (shapefiles)"
}
},
"data": {
"type": "file",
"format": null,
"file": "sample.kml"
},
"tasks": []
}
}

Apparently the geoserver don't accept the relative path like it says on the API documentation.
If instead of:
"data": {
"type": "file",
"file": "./data/sample_dir/sample.kml"
}
I use
"data": {
"type": "file",
"file": "/var/lib/tomcat7/webapps/geoserver/data/sample_dir/sample.kml"
}
on the request it works fine.
