Redirect configuration doesn't work

I'm configuring a route in order to redirect from "/directus" to "/directus/", and the SWA only ever 404's

Configuration

```json
{
"routes": [
{
"route": "/*.{css,js,png,jpeg,jpg,webp,svg,ico,json}",
"headers": {
"Cache-Control": "public, max-age=31536000, immutable"
}
},
{
"route": "/directus",
"redirect": "/directus/",
"statusCode": 301
},
{
"route": "/directus/index.html",
"redirect": "/directus/",
"statusCode": 301
},
{
"route": "/directus.html",
"redirect": "/directus/",
"statusCode": 301
}
],
"responseOverrides": {
"404": {
"rewrite": "/404.html"
}
},
"forwardingGateway": {
"allowedForwardedHosts": [
"someloantest-cffffeweqqq.z01.azurefd.net"
]
}
}
```
