> @wangyang0918 Do you have any idea why the CI test `CI / e2e_ci (Default
configuration, default, flink:1.13, v1_13) (pull_request) ` is braking? Made a
simple test locally to see if it has anything to do with parsing the response
body, without luck so far:

"{\"refresh-interval\":3000,\"timezone-name\":\"Coordinated Universal
Time\",\"timezone-offset\":0,\"flink-version\":\"1.13.6\",\"flink-revision\":\"b2ca390

I managed to debug this issue locally finally on an older mac (there's no
Flink v1.13 for silicon :/). It is indeed an 501 on the first try, then a JSON
parsing issue on the retries. (The error handling in the rest client is a mess,
the client side errors are swallowed completely) I'll try to come up with
something tomorrow:
```
org.apache.flink.shaded.jackson2.com.fasterxml.jackson.databind.exc.MismatchedInputException:
Cannot map `null` into type `boolean` (set
DeserializationConfig.DeserializationFeature.FAIL_ON_NULL_FOR_PRIMITIVES to
'false' to allow)
at [Source: UNKNOWN; line: -1, column: -1] (through reference chain:
org.apache.flink.runtime.rest.messages.DashboardConfiguration["features"]->org.apache.flink.runtime.rest.messages.DashboardConfiguration$Features["web-cancel"])
```
This makes more sense ^^^ than the ones I saw in the CI logs.
