The first error I see in the sessiond logs is:
DEBUG3 - 21:31:07.825293221 [8383/8531]: UST app context 5 allocated (in alloc_ust_app_ctx() at ust-app.c:1161)
Error: UST app create channel context failedh for app (pid: 8601) with ret -1024
Does the issue still happen without the perf contexts ?

Also, having a log of "lttng-sessiond -vvv --verbose-consumer" would be useful.

Without the performance counters, it "works". Traces can be read in trace compass and babeltrace2.
Babeltrace1 has the following output:
$> babeltrace -vvv .
