Problem converting Turf Feature to GeoJSON?

Hi, I have this code:

    func jsonToString(geoJSON: GeoJSONObject) -> String? {

        do {
            let encoder = JSONEncoder()
            let data = try encoder.encode(geoJSON)

            if let jsonString = String(data: data, encoding: .utf8) {
               return jsonString
            }
        } catch {
            // Handle error
        }
        return nil

    }

    func getMapImageUrl(bulletin: ContextualBulletin?, bw: Bool) -> UIImage? {
        if bulletin == nil {
            return nil
        }

        let publicationTime = bulletin!.data.publicationTime
        let region = bulletin!.data.bulletinID

        let accessToken = "my token"

        let size: CGSize
        switch (family) {
        case .systemSmall: size = CGSize(width: 626 / 2, height: 313 / 2)
        case .systemMedium: size = CGSize(width: 1242 / 2, height: 936 / 2)
        case .systemLarge: size = CGSize(width: 2478 / 2, height: 1404 / 2)
        default: fatalError("not supported")
        }

        let regionIDs = bulletin!.data.regions.map { $0.regionID }

        let options = SnapshotOptions(
            styleURL: URL(string: "mapbox://styles/fezvrasta/clnlphb2q004901qyexsybaqo")!,
            size: size
        )

        let firstRegion = regionIDs.first!
        let dangerRating = bulletin!.data.dangerRatings.first!
        if let elevation = dangerRating.elevation,  let feature = getFeatureByRegionIdAndElevation(
           regionID: firstRegion,
           elevation: elevation
        ) {

            let geoJSONString = jsonToString(geoJSON: feature.geoJSONObject)
            let geoJSONOverlay = GeoJSON(objectString: geoJSONString!)

            options.overlays.append(geoJSONOverlay)

        }
        let snapshot = Snapshot(
            options: options,
            accessToken: accessToken)

        if let image = snapshot.image {
            return image
        } else {
            print("no image")
            return nil
        }
    }

But I'm always ending in the no image branch.

The same geo jsons are working fine on the iOS Mapbox SDK v11

Am I doing something wrong? The stringified json looks correct to me:

It's 713 coordinate points

I also tried with a Gist using your example but I get the same problem:

let geoJSONOverlay: GeoJSON

do {
  let geoJSONURL = URL(string: "https://gist.githubusercontent.com/FezVrasta/e587d59b09d1b5920aa391224d8664ba/raw/b403f06c73ee139cf27ed0aa463603ceb73158a5/gistfile1.txt")!
  let geoJSONString = try String(contentsOf: geoJSONURL, encoding: .utf8)
  geoJSONOverlay = GeoJSON(objectString: geoJSONString)

  options.overlays.append(geoJSONOverlay)
}

It happens even with a version with way less points: https://gist.githubusercontent.com/FezVrasta/5816d4d519ee147836ec0da2aeb0467a/raw/8d40f4776fb0f82a3c91a52adafbbf2f9306034e/gistfile1.txt

I also tried a feature collection and setting the stroke, stroke-width, stroke-opacity, fill properties, but still it errors:

{"features":[{"type":"Feature","geometry":{"type":"Polygon","coordinates":[[[10.66419272879387,46.09254566028145],[10.664147159156835,46.09222861163446],[10.662934992546054,46.09148446384751],[10.660225443651095,46.09069069506981],[10.655875904635925,46.090343417614356],[10.650670718600935,46.090194583745195],[10.644253365955521,46.08954963230871],[10.63690906237206,46.08811086713693],[10.632345611601783,46.08706897912315],[10.626997817730457,46.08567976429429],[10.623789141407663,46.084687446429825],[10.62214915128715,46.08379434499154]]]},"properties":{"stroke-opacity":1,"stroke-width":3,"stroke":"#00f","fill": "#00f"}}],"type":"FeatureCollection"}

I only managed to make work a LineString, but I really need a MultiPolygon...

{"features":[{"type":"Feature","geometry":{"type":"LineString","coordinates":[[10.66419272879387,46.09254566028145],[10.664147159156835,46.09222861163446],[10.662934992546054,46.09148446384751],[10.660225443651095,46.09069069506981],[10.655875904635925,46.090343417614356]]},"properties":{"stroke-opacity":1,"stroke-width":3,"stroke":"#00f","fill": "#00f"}}],"type":"FeatureCollection"}

So, this doesn't render:
