Did you enable the flamegraph feature in the configuration?

Hi community,
Flink 1.13.0 releases flamegraph. However, when I run Flink 1.13.0
locally, and try to check the flamegraph of an operator that is
running, I got this "404 not found" error. This is the request and
response.

This can be consistently reproduced regardless of what job I run.
Any idea why? Thanks!
