If you're using `rosbag` in the web (or importing `rosbag/dist/web/index.js` directly) modify the lines

```js
// open a new bag at a given file location:
const bag = await open('../path/to/ros.bag');
```

to

```js
// get a file blob from the file location:
const blob = await fetch('../path/to/ros.bag').then((r) => r.blob())

// open the file blob:
const bag = await open(blob)
```

The rest remains the same.
