HUD no longer loads reliably

[psiinon]

The HUD often fails to initialise correctly when Firefox or Chrome are launched.
When this happens only the green "plus" buttons are shown in the left and right panes.
This will need to be fixed before we can move the HUD back into supported status.
Comment if you're interested in looking at this.
Its probably a non trivial problem, so no problem with more than one having a go...

Hi,

I am now willing to look into HUD, since it is not being maintained at all so I can make some progress in it.
Can you give me some pointers on where should I start from?

Grab the latest add-on from the marketplace. Ensure it’s enabled. Open a browser from within ZAP and see if you can trigger the issue.

Assuming you can then check the ZAP logs and browser dev tools console and see if you can sort out and correct the issue.

Hi,
I cant seem to reproduce the errors, even though HUD is still not loading. I am on Mac M2, opened a browser with HUD and couldnt see anything on browser but Cannot GET /OTHER/quickstartlaunch/other/startPage/.
Browser console is empty and zap log also dont mentions the opening of HUD or any errors associated with it, just the updation of add-ons I did before it.

Had you navigated somewhere or were you just sitting on a blank page? You need to navigate somewhere for HUD to kick in.

ah, now I get it.
HUD is working fine with me on both firefox & chrome (but the console is full of errors). Is there any specific version of browser HUD is crashing on?
Plus, I would like to know the working of zap.log file, when is something logged to it? Is opening of browser gets logged to it? I still cant see any new additions in log file.

[psiinon]

I dont see any HUD crashes, instead it often doesnt load correctly.
The symptoms are most of the side buttons missing - only the "green plus" ones being shown.
However its not consistant.
Try launching it repeatedly on both Firefox and Chrome - the first few times it loaded fine for me but then I saw a couple of failures.
The zap.log file is written to from the Java code - we use Log4J and if you switch to DEBUG level you'll see a load of messages..

The dev build is not showing home screen on launch to open up browser, is there any option to get it manually?

[kingthorin]

Install the Quick Start add-on

Thanks @kingthorin.

On launching HUD from source using ./gradlew runZap it fails with message ZAP did not fully start after 90 seconds, cause: Unable to connect to ZAP's proxy after 90 seconds.
Interestingly the ZAP still runs and HUD is also working fine in it, any idea what's causing the build to fail here?
