Uncaught TypeError: Path must be a string. Received null

[ryancole]

[Enter steps to reproduce:]

1. Honestly, I'm not sure. I'm simply saving a .js file, with format-on-save enabled. This was working like 10 minutes ago but is no longer working. After receiving the error a first time, I was prompted to updated Atom. I updated Atom and am still getting the error.

Atom: 1.14.4 x64
Electron: 1.3.13
OS: Microsoft Windows 10 Pro
Thrown From: prettier-atom package 0.21.0

This is happening to me as well. It started occurring upon upgrading prettier-atom to 0.21.0

[robwise]

I'm on it!

@ryancole & @skevy if you just create an empty .eslintignore file in your project, the error goes away...
just a dirty workaround until @robwise fixes this...

[thtliife]

Wow @robwise that was FAST!
Loving this package btw.... :)

[robwise]

@thtliife @ryancole @skevy I just released a new version that hopefully addresses the bug. I apologize; I had to change a bunch of stuff under the hood when integrating prettier-eslint and this bug crept in.

Could you update to the latest and verify that it fixes your use cases? I was able to reproduce locally and then my fix seemed to resolve it, but I just want to make sure you're all set.

Wow @robwise that was FAST!

So happy to hear it!

[techrah]

I'm getting the same issue on version 0.21.1 but an empty .eslintignore does the trick.

[robwise]

Okay, was a double bug, fixing that now

[robwise]

I was able to reproduce the eslintignore problem as well and wrote a fix that seems to resolve it. I got thrown off because I actually encountered and fixed an unreported bug the first time. This should now fix the actual bug you were describing. I just published 0.21.2. Can someone confirm the problem is solved?

[thtliife]

Confirmed fixed in v0.21.2
Thanks for the fast work @robwise :)

[skevy]

Thanks @robwise for the quick turnaround!!

[kentcdodds]

Thanks @robwise! Take care of yourself :)
