Crashes on open with invalid config

[sambass1]

• I am on the latest Hyper.app version
• I have searched the issues of this repo and believe that this is not a duplicate

• OS version and name: <macOS Sierra 10.12.3>
• Hyper.app version: <Hyper 1.2.1>

When I open Hyper the terminal open and closed quickly. The app is still open however. When I click on preferences in the menu bar the below pop up box shows. I've tried uninstalling and reinstalling but same problem occurs.

A JavaScript error occurred in the main process
Uncaught Exception:

How did you uninstall the app? You could try https://freemacsoft.net/appcleaner/
And then reinstall. Have 10.12.2 and can't reproduce the issue. Not sure when i will have time to upgrade to 10.12.3

I used appcleaner to remove it and still the same issue. Also installed the older version of Hyper and the same problem.

I think it's an issue in the preferences but I can't edit those without using the terminal.

I had a similar (ish-)issue. #1581
Exact same symptoms.
In my case the plugins array had an extra comma in it.
My solution was to open the ~/.hyper.js file in a regular editor / other terminal. then make sure the file has no typos in in....

Your situation seems to be different, I'd start by removing all the plugins, then re-adding them one by one (I'm going on the assumption that the issue is plugin related)

Hope this helps.

Great, advice. Opened the ~/.hyper.js file in a regular editor and changed what I needed. Working fine now. Thanks @rohan-buchner

I think we should handle that error and show a nice alert so next time the user knows that there's something wrong in the Preferences👍🙌

I'm having this exact problem with Windows. I also see other issues listed. I made a backup of my config before I changed it to use powershell. I'm now assuming one of my args is wrong because it just throws an uncaught exception on startup.

I could roll back my config, or try again but it isn't clear where this config file is in Windows. A reinstall cleaning the app folder makes no difference either, if you reinstall, something is lingering because it just throws again.

I am having the same issue, mine did not trigger until i misspelled the address for bash and i tried editing the config again, no such luck so i uninstalled went back version etc, still the same error

[Anzumana]

will give it a try. and see if i can find a good solution for this issue

Same issue on Windows.

They also have this error in the VS Code terminal and here's how they handle it. I guess listening to that error and noticing the user should be fine until something better comes up.

I have encountered this same error call stack as OP with Hyper 2.0.0 on Windows 10, but not on start up, instead whilst attempting to Ctrl+C to exit top inside an SSH session started from the Bash on Windows shell.

Hi, you have to search for hyper.js file in your system and edit it by your need delete all the code if you don't know what is causing the error
I hope that will help
