Accessing fields that contain a special character

[yxyx520]

json like blow, how to get the value of "b/c"?

{
  "a": {
    "b/c": 2
  }
}

I try some transforms config blow but failed:

• .a.b/c
• .a.'"b/c"'
• .a'."b/c"'
• .a["b/c"]

most error like unexpected end of query path

when I use jq to accessing fields I succeed

$ echo '{"a": {"b/c": 2}}' | jq .a.'"b/c"'
$ 2
$ echo '{"a": {"b/c": 2}}' | jq .a'."b/c"'
$ 2

In kubernetes, there are some lables with "/", such as "app_kubernetes_io/name" and "app_kubernetes_io/component", I do not find any method to get those values with "/" in key.
