Dirac window is blank on startup in Dirac 1.2.38

[aeberts]

Environment
Dirac Version 1.2.38
Chrome Canary Version : 71.0.3547.0
Mac: 10.11.6
Java: "1.8.0_101"

Issue:
Dirac window is blank when starting Dirac 1.2.38 on above environment.

Expected behaviour: Dirac starts normally

Actual behaviour: When clicking Dirac extension button in Chrome the Dirac window appears but it is blank. The following errors are displayed when choosing: View >> Developer >> Developer Tools >> Console when the blank Dirac window is displayed:

Reproduction Steps:

• Update Dirac extension to 1.2.28
• Start Chrome Canary with remote debugging enabled
• Start re-frame application, nrepl and dirac agent as outlined in installation instructions
• Click Dirac extension icon in Chrome
• Result => Dirac page is displayed but the window is blank. The above mentioned error message is displayed in the Developer Tools console for the Dirac window.

Additional Notes:

• This project was working correctly with Dirac 1.2.27 on my laptop running Mac 10.13.6.
• Restarted Chrome and did a lein clean and restarted figwheel servers => same result.

Thanks for reporting. I was able to reproduce the problem. It looks like something very weird happened when I compiled dirac in advanced mode. I was doing some experiments around issue #81 and maybe some cljs compiler caches stayed dirty when producing final build or something...

I just released a proper build as v1.2.39.

It might take a while before updated version appears in chrome web store. In the meanwhile you might want to download the zip archive from github release page and drag&drop it onto your chrome extensions page.

Not sure what exactly happened, but I guess that changing cljs compiler from 1.10.339 to 1.10.415 (a local build) and then back to 1.10.339 and building advanced build caused it. Some compiler caches might have been incompatible/confused when produced by newer compiler and then consumed by old one. Just a theory. I did clean all caches I know about and new build seems to work as expected.
