panic when start traefik with bolt backend #1795
Description
Do you want to request a feature or report a bug?
bug
What did you do?
I attempted to use the boltdb backend to configure traefik.
I added the following keys to the "traefik" bucket.
/traefik/backends/srv2/servers/server_1/url http://127.0.0.1:32001
/traefik/frontends/srv2/backend srv2
/traefik/frontends/srv2/routes/test_1/rule Host: srv2.test.loop
What did you expect to see?
I expect that traefik starts or returns a error what is wrong in the configuration.
What did you see instead?
panic: runtime error: slice bounds out of range
