Is there a backtrace you can copy/paste in the developer console (Help -> Toggle Developer Tools)?

[tylerlu94]

Sorry about that. Here it is

Also the issues seem to get resolved after restarting the extension

Thanks, @tylerlu94. The root cause appears to be related to variable assignments with literal types, e.g., var = [] or @var = 'var'. I'll work on a fix for the next release.

[castwide]

@tylerlu94 Are you still experiencing this problem? I'm no longer able to reproduce it using gem v0.32.0.

[tylerlu94]

Haven't run into this issue since the update. Thanks!
