Unhandled promise rejection on startup

[ecciv]

Not sure what's up but each time I open Parsify, I get an error like this, and the input side of the app is replaced by a white box saying "An unexpected error occurred.". Can't get it to run! On 1.4.1 now, this error is new to me.

Unhandled Promise Rejection
TypeError: Cannot read property 'value' of undefined
at IpcMainImpl. (C:/Users/Victor/AppData/Local/Programs/parsify-desktop/resources/app.asar/app/background.js:1:11092)

If you care about your configuration, you can modify the preferences.json file inside the Parsify Desktop folder, which is located in %appdata%. Open it with any editor and add a missing property (do not include the + symbols):

{
	"preferences": [
		...
	      {
		  "name": "configuration",
		  "value": ""
+	      },
+             {
+	          "name": "fontSize",
+	          "value": "1rem"
+             }
	],
	...
}

If you don't manage to do it, just sent me this file to my email ([email protected]) and I will do it for you.

In case you don't really care about your configuration, go ahead and just delete the whole Parsify Desktop folder inside %appdata% - the configuration will reset and everything will work fine.

I'm sorry about this inconvenience, but this is an issue with the problematic user configuration storage used in Parsify Desktop. I'm thinking about using a different solution for that in the upcoming release, so that such problems won't occur in the future :)

Thanks! I got it to work.

Also I was trying out to see if Parsify will solve equations and the input side crashes when I write solve(-any equation here-). What's up with that?

@ecciv Glad to hear that it works 😄 Parsify currently does not support equation solving (for example x + 2 = 3). I would really like to support it, but currently, it would be incredibly hard to implement. But because the math parser in Parsify is based on Math.js, they might implement it at some point, as it seems like a requested feature (see josdejong/mathjs#38 and mentioned issues/PRs).

The configuration storage was completely refactored in version 1.5.0 and this issue will no longer occur. Please update 😄
