Error: Input data is not a valid GeoJSON object

[Dutisto]

Hi,
I'm trying to use this tool but I always get that error : Error: Input data is not a valid GeoJSON object
I've tested with multiples geojson, and some from http://geojson.io . Nothing seems to work out.
I'm using the same code as in the README.md :

// build an initial index of tiles
var tileIndex = geojsonvt(geoJSON);

// request a particular tile
var features = tileIndex.getTile(z, x, y).features;

// show an array of tile coordinates created so far
console.log(tileIndex.tileCoords); // [{z: 0, x: 0, y: 0}, ...]

Any advices ?

Try putting your GeoJSON into http://geojsonlint.com/ and seeing if it has any problems.

I'm trying to use a very simple geojson, verified on geojsonlint.com :
{
"type": "FeatureCollection",
"features": [
{
"type": "Feature",
"properties": {},
"geometry": {
"type": "Polygon",
"coordinates": [
[
[
1.8017578124999998,
50.68949806239989
],
[
1.64794921875,
50.72341622356851
],
[
1.7509460449218748,
50.4758608877373
],
[

[

50.566666077402395
],
[
2.13958740234375,
50.59805794433924

1.8017578124999998,
50.68949806239989
]
]
]
}
}
]
}

The content of my main.js :

var geojsonvt = require('geojson-vt');

var fs = require("fs");

var content = fs.readFileSync("miss.geojson").toString();

// build an initial index of tiles
var tileIndex = geojsonvt(content);

// request a particular tile
var features = tileIndex.getTile(19, 50.611103, 2.96086).features;

// show an array of tile coordinates created so far
console.log(tileIndex.tileCoords); // [{z: 0, x: 0, y: 0}, ...]

And still the same error

@Dutisto you're passing a string to geojsonvt, and it expects a JSON object. You should do geojsonvt(JSON.parse(content)).

Oh, so that's really a dumb mistake. Thanks for the help !
