使用boltdb后端启动traefik时出现恐慌

Question

I'm trying to start traefik with the boltdb backend. Sadly I always get a panic. Following my setup and the terminal output.

Start Command

./traefik_darwin-amd64 -d -c config.toml

config.toml

debug = true
defaultEntryPoints = ["http"]
[entryPoints]
  [entryPoints.http]
  address = ":8081"

[web]
address = ":8082"

[boltdb]
endpoint = "/Users/tochti/Tmp/traefik.db"
watch = true
prefix = "/traefik"

Terminal Output

After a long time of waiting the following panic is displayed
