Hi, this looks like a duplicate of an really recent issue. Can you tell us if it's different than #1961?
If you could follow the issue template next time, we might be able to identify the issue much faster.

I have no plugins installed but still see the error...

[timothyis]

Right, the error is the same as the issue I linked, hence the assumption.
What operating system are you on? Which Hyper version are you on? Are you sure you have no plugins/themes? Hyper should be black by default and it looks like yours is themed.

Does it load after a few minutes? I'm seeing a startup time of several minutes all the sudden and I'm on fish too.

Hello! Happening to me too, on a fresh install of ubuntu + hyper (no plugins installed).

• Ubuntu 17.04
• installed fish through apt and set as my default shell (chsh)
• installed hyper using latest .deb file 1.3.3
• won't start, console shows above mentioned error (Uncaught TypeError: Cannot read property 'substr' of null)

I'm also experiencing this, probably 75% of the times I start the app. Sometimes it works fine, other times it just freezes there and shows that error in the console.

I added some debugging console.log() calls before line 14037 of node_modules/hterm-umdjs/dist/index.js to see what the values involved were:

index.js:14037 this.foreground: ""
index.js:14038 this.defaultForeground: null
index.js:14039 colorToMakeFaint: null
index.js:463 Uncaught TypeError: Cannot read property 'substr' of null

    at hterm.Terminal.interpret (index.js:11698)
    at __WEBPACK_IMPORTED_MODULE_2_runes___default.forEach.rune (hterm.js:134)

It seems like the foreground and defaultForeground properties of that particular hterm.TextAttributes instance aren't getting set before the syncColors method is called.

I also added a throw there if colorToMakeFaint is null, and was able to get a bit more of the stack:

Uncaught Error: colorToMakeFaint is null!

I was able to hack around the problem by adding the following before line 14037 of node_modules/hterm-umdjs/dist/index.js:

    if (colorToMakeFaint === null) {
      console.warn("colorToMakeFaint is null! Changing to black.");
      colorToMakeFaint = 'rgb(0, 0, 0)';
    }

---

Aside from that hack, I'm not sure how to proceed in debugging this past this point... any ideas?

Problem still persists in 1.4.3

Hey there, please try again with the new Hyper v2 release and open a new issue if the problem stills exists. Thank you!
