Uncaught TypeError: Cannot read property '0' of null

Problem
Athens is crashing on my system, macOS version 11.2.2. I'm using Athens 1.0.0-beta.46. The error happens when I try to update to version 1.0.0-beta.47.

message=Uncaught TypeError: Cannot read property '0' of null
source=file:///Applications/athens.app/Contents/Resources/app.asar/resources/public/js/compiled/renderer.js
lineno=15103
colno=505
error=TypeError: Cannot read property '0' of null

Screenshots

Athens Version
1.0.0-beta.46

That’s super strange. Not at my computer right now. Will look into this tomorrow. In the meantime, you can download the latest version directly by using the same Mac download link or rollback to a previous version. Steps are somewhere on discord #troubleshooting I believe.

I've updated manually to version 1.0.0-beta.47 and that works fine. If no one else sees this issue, I guess we can close it.

I had this issue too from Linux. After restarting, it worked though.

also occured on Windows, but the installation went through (showing a couple more error messages, though)

I also encounter this message after clicking the update prompt. After seeing the same message and press "OK", the app turned blank. I just leave it be and seems like Athens still updated itself under the hood and quit afterward. When I restart Athens it is the 1.0.0-beta.47 version. I would suggest a better visual for the update process and automatic restarting after updates.

Got the same error on Big Sur.

Seems like the issue is actually coming from renderer, and only when an update is found. Not a crippling issue, as the update still ends up happening.

Sentry gives a more verbose error message:

TypeError: Cannot read property '0' of null

This takes us to

Same error happened to me on beta.49. Downloaded new version from github link and installed successfully, as suggested by others.

Closing this because this is an issue for past built, we expect a new issue to be created if this bug occurs in later builds so that they can be solved with P0 (highest) priority.
