Argument of type 'string | ArrayBuffer | Blob | number[] | Uint8Array | Buffer | ReadableStream' is not assignable to parameter of type 'Blob | MediaSource'.

Nobody has claimed this yet.

I keep getting this typescript issue here below on this line `const url = URL.createObjectURL(blob);`

> Argument of type 'string | ArrayBuffer | Blob | number[] | Uint8Array | Buffer | ReadableStream' is not assignable to parameter of type 'Blob | MediaSource'.
Type 'string' is not assignable to type 'Blob | MediaSource'.ts(2345)
const blob: string | Blob | number[] | Uint8Array | ArrayBuffer | Buffer | ReadableStream

```
const convertToShapefileAndDownload = async (geoJson) => {
try {
if (!geoJson || typeof geoJson !== 'object') {
throw new Error('Invalid GeoJSON data');
}

const options: any = {
folder: 'plots',
types: {
point: 'points',
polygon: 'polygons',
polyline: 'lines',
},
compression: 'STORE' as any,
outputType: 'blob',
};

const blob = await shpwrite.zip(geoJson, options);
const url = URL.createObjectURL(blob);
const link = document.createElement('a');
link.href = url;
link.download = 'plots_shapefile.zip';
document.body.appendChild(link);
link.click();
document.body.removeChild(link);
URL.revokeObjectURL(url);
} catch (error) {
//handleNotification(error, 'error');
console.error('Error converting to Shapefile:', error.message);
}
};

```

Start at the shpwrite.zip entry point and inspect the type declaration or implementation for its outputType option. Reproduce the TypeScript error with outputType: 'blob', then verify the package's reported return type matches the value produced and that the example can pass it to URL.createObjectURL without the reported error.
