Flow-for-vscode: Odd flow behavior

[johnkorzhuk]

Flow is working for me, but I noticed it sometimes is slow. In the output I see the follow:

[2017-04-25T13:02:38.227Z] [ERROR] flow - Unknown return code from Flow: 10

The relevant bit seems to be "exitCode":10,"stderr":"File not found: /Users/johnkorz/Documents/prac/redux/udemy-sg/blog-posts/extension-output-#3\n","stdout":""} but I'm not too sure what that means.

Also whenever I focus the output window in vscode it starts spamming those errors. When I focus another window it stops and outputs [2017-04-25T13:02:38.698Z] [INFO] flow - [ready]: Flow server in /Users/johnkorz/Documents/prac/redux/udemy-sg/blog-posts

[matthewchung74]

Same here. Is there a workaround for this?

[f0und3r]

Same

[peterschussheim]

I am receiving the same Unknown return code from Flow: 10 using latest extension and vscode insiders build.

Solved this issue for me by deleting the flow-typed directory. Running flow-typed install afterwards caused no problems. Happened twice now already.
