Flame: v8 log conversion failed

[ttessarolo]

Expected Behavior

Generate and open Flamegraph

Current Behavior

Error: v8 log conversion failed

Steps to Reproduce (for bugs)

0. I'm using a basic node.js app just for test:

var express = require("express");
var app = express();

app.get("/", function(req, res) {
res.send("Hello World");
});

app.listen(3097);

1. using Node.js v.10.10.0 (with both clinic doctor + autocannon installed -g)
2. clinic flame --on-port='autocannon -c 100 localhost:$PORT' -- node index.js
3. when autocannon finish it produce the following error: Error: v8 log conversion failed
4. Switching to Node.js v8.12.0 -- nvm use v8.12.0 -- (with both clinic doctor + autocannon installed -g) and running exactly the same command it generates correctly the flamegraph

Thanks for reporting, this is actually a regression in Node.js 10 which will be fixed in 10.11, coming out later today.

@mcollina - Should this and the related 0x issue be closed since the fix is released into Node?

While I'm not @mcollina (who could be! ;-) ) I definitely think we can close this one
