TypeError: Body has already been consumed.

How it happens:

vue-router displays Changelog.vue
loading main page "home" then trying to load "changelog" page.
error doesnt happen when loading changelog page first.

Error:

`TypeError: Body has already been consumed. vendors~Changelog.js line 175 > eval:427:20`
`return res.text();`
Error location:
```
methods:{
fetchFile: function fetchFile() {
var _this = this;

var changelog = this.changelog || '/CHANGELOG.md';
__WEBPACK_IMPORTED_MODULE_0_unfetch___default()(changelog).then(function (res) {
return res.text();
}).then(function (res) {
var _fm = Object(__WEBPACK_IMPORTED_MODULE_1__utils_front_matter__["a" /* default */])(res),
body = _fm.body,
attributes = _fm.attributes;

_this.site = attributes;
_this.html = Object(__WEBPACK_IMPORTED_MODULE_2__utils_markdown__["a" /* default */])(body, {
site: _this.site,
colors: Object.assign({
Fix: '#b26cee',
New: '#3778ff',
Breaking: '#ff9800'
}, _this.colors || {})
});
});
},
getDomain: function getDomain(url) {
return url.replace(/^https?:\/\//, '');
}
}
});
```

Changelog.vue

```

import { LogLive } from "loglive";
export default {
name: "changelog",
components: {
LogLive
},
data() {
return {
changelog: "/CHANGELOG.md"
};
},
mounted() {}
};

@import url("../css/loglive.css");
#changelog-container {
min-height: 100vh;
max-width: 50%;
margin: auto;
padding: 0 10px;
}

```

Start with Changelog.vue and reproduce the reported navigation from the home page to the changelog page, then trace the LogLive fetchFile path shown in the error. Done means opening Changelog.vue after the home page renders the changelog without the “Body has already been consumed” TypeError.
