Endpoints 404 when adding a slash

Endpoints 404, if you add a / at the end of the URL

Expected behavior

When calling an endpoint (in my case /trackservice) it shouldn't matter if the URL ends with a / or not.

So /trackservice and /trackservice/ should work the same.

Actual behavior

When calling /trackservice/ engine-api returns a 404-error:

{
  "detail": "The requested URL was not found on the server. If you entered the URL manually please check your spelling and try again.",
  "status": 404,
  "title": "Not Found",
  "type": "about:blank"
}

Calling /trackservice works as expected.

To circumvent this in the reverse-proxy of dashboard, I've had to add two locations, as seen in this commit: dashboard@dabb7599

The second location (for current) wouldn't be necessary without this issue.
