Thanks!

This exception is caused by Rodeo trying to use a port that something else is using, and falling on its face. It would be better if it detected that and then picked a different port, but I haven't had time yet to work on this. Any PRs welcome. : )

Restarting Rodeo will pick another random port, and it'll work.

Not sure that I have the same issue, but it repeatedly fails on startup on Ubuntu 16.04. Doesn't report an uncaught exception, but has something to do with ipc-promises.

That log is saying that something between the main process (the one running the python commands) and the browser process (the one drawing in the browser) didn't return a value, but one was expected.

There is probably an error above that which is causing the failure.

The problem seems to have disappeared after reboot, so, unfortunately, I can't provide more details.

https://www.npmjs.com/package/find-port - might be able to make use of this NPM to test a given range of port values. I did notice some hard-coded 3001 entries in the webpack.* files, but this is also the first time I've really looked at the codebase, so I'm not sure which pieces of the app require the knowledge of the used port value.

Hey Erik! Nice idea! You should totally make a PR. :D Otherwise, I'll add this myself in a bit.

working on it, working on it

[erikyuzwa]

speaking of ports, also funny that the issue number is 443.

[ironspecs]

Haha, yeah, good eye.

As a fellow UI developer, I'm really curious about what you think of the rest of the app as well!

[erikyuzwa]

🙇 just diving into this codebase but it definitely looks interesting. Electron is EVERYWHERE!! I love it!
