Error: Could not parse ATrace line "CPU:3 [LOST 4262 EVENTS]"

I'm getting error Error: Could not parse ATrace line "CPU:3 [LOST 4262 EVENTS]"
in
And parent call happens from:
Currently I fixed it with next construction:
let output;
try {
output = frameTimeParser.getFrameTimes(atrace, pid);
} catch (e) {
console.error(e);
}
if (!output) {
return;
}
const { frameTimes, interval: atraceInterval } = output;
In my opinion it's better to ignore one frame rather than crash the profiler.
The exception happens when I just launched emulator and run a lot of tests sequentially, the test execution is several seconds, then I do a short break (maybe 100ms) and repeat a test.
This is a full stack trace, but don't look at number of lines - I applied a patch, so some of line numbers are not correct:
Error: Could not parse ATrace line "CPU:2 [LOST 8693 EVENTS]"

Hi @kirillzyusko, apologies for the delay! We're usually faster than this

Yep, I agree, that makes a lot of sense!
Do you want to submit a PR to add your patch? I can pull them along with your other change in the next releases.
@Almouro Yeah, sure. I'll submit a PR today 🙌
