Looking at the stacktrace, it seems that the perfetto trace processor is not reachable anymore. Can you please check if there is any other log in the stacktrace tagged perfetto or trace_processor?

Thank you for looking into it - should I be looking into logcat logs or Gradle output?

In the logcats: there should be some failure/crash of the perfetto trace processor http server

Facing the same issue on benchmark alpha13

I think aosp/2549513 should solve the issue. I believe the problem is in the trivial http request implementation.

The fix will be in the next alpha.

The following release(s) address this bug.It is possible this bug has only been partially addressed:

• androidx.benchmark:benchmark-macro:1.2.0-alpha14
