Getting a similar Error using webstorm and windows 7
Same error here, using WebStorm integration.
Still the same messages - Flow 0.65 (ping)
same here
similar with PhpStorm 2017.3.4 and Flow 0.65 and MacOS:

Same with latest Flow 0.66
Error still occurs with latest flow version and PhpStorm 2018 EAP
Same here. flow 0.66
Same here. flow 0.67.1 MacOS X 10.13.3 WebStorm 2018.1 EAP and 2017.3.5
flow 0.68 same thing
@mroch According to above comments, "Windows support" label should be removed. (Crashes on Mac as well)
@levenleven I didn't do it! I have no labeling rights.
flow 0.68 same here MacOS X + WebStorm 2018.1 EAP and 2017.3.5
Lwt is a library that Flow uses. It's basically promises for OCaml. So unfortunately most the stacks collected here are for different issues.
@lll000111's first two stack traces shows that each time we start up a Flow server, it crashes due to "Dfind_died". Dfind is the file watcher Flow uses. It sounds like it might be less than stable on Windows for some reason. It looks like #4960 is tracking the dfind dying issue.
@dcgudeman's stack trace shows the server's connections to ephemeral commands (one-off requests, like flow status
and flow type-at-pos
) are being closed before we expect. Not fatal errors. I wonder if PhpStorm is maybe killing some commands before they finish? How does this affect the user experience? If there's no user-visible effect, I'd just recommend ignoring this part of the log. If there is a user-visible effect, could you report it in its own issue?
Since this issue is kind of ending up as a catch-all, I'm going to close it out.
@gabelevi As most flow issues this one just closed without resolution. Open another one and it will be closed the same way in a few months. How does this affect user experience? - flow fails to start.
I'm having the same issue suddenly, launching flow
directly from command-line (Windows 7 Enterprise, flow-bin
v0.67.1). Weirdly enough it started exhibiting after I've spend quite a bit of time updating to the latest flow-bin
throughout our whole codebase.

So ... I found the real culprit in my case by running flow check
, which prints out the full stack trace directly.
Turns out Flow was crashing when trying to parse node_modules/module-deps/test/invalid_pkg/package.json
, because it contains just a string, not an object. Adding .*/node_modules/module-deps/.*
to [ignore]
in .flowconfig
fixed the problem.
@hon2a can you file a new issue specifically about the crash parsing JSON? thanks :)
@mroch Sure thing! Here you go: #6049 .
Found on Windows 10, Flow 0.62, run through WebStorm - also see WS ticket https://youtrack.jetbrains.com/issue/WEB-30395
