Analysing dataError: premature close

[juanTurk]

I have a problem rendering the results in a big proyect. I'm using node version 16.15.1

Comand run:

clinic bubbleprof -- node index.js

Error:

[=== ] Analysing dataError: premature close
    at onclosenexttick (.../.nvm/versions/node/v16.15.1/lib/node_modules/clinic/node_modules/end-of-stream/index.js:53:86)
    at processTicksAndRejections (node:internal/process/task_queues:78:11)

Any idea if there is an alternative solution for this problem?
Thanks

Unfortunately, this is a known issue in the end-of-stream library, while it wasn't fixed yet I suggest:

• remove .clinic/ folder
• remove node_trace* files

and collect more data before closing the process.

I encountered the same problem on clinic v11.1.2 and bubbleprof v8.0.1. cleaning the directory does not work. I have patched end-of-stream with mafintosh/end-of-stream#13 and the premature close error is fixed. but when I load generated HTML, It is stuck in the loading state.
btw, clinic doctor and flame work perfectly.

@eyousefifar I've got the same problem here. I thought it was taking too long because of my computer, but it looks like it hangs no matter what...

Same here 😢

Can't use bubbleprof. Cleaning as suggested. Running autocannon for 5 minutes, no matter what.

Same problem here with clinic doctor.

My script had a lot of promises that were not awaited but I simply expected to be waited on at the end of the script by the Node runtime. Normally this works, but it seems to be what's causing the issue here.

I was able to fix it by collecting all my promises in an array, and then running await Promise.all(my_promise_array) at the end.

I'm not sure how this solution would apply to non-script cases like a webserver, but hopefully it helps some of you.
