Regression on 8 of November 2021 - was the CDN version changed?

Hi,
Today we have 4-5 builds that failed with the same problem. The test is connected with pointer click events.
On our side the last commit in this project was Wed Aug 25 23:23:27 2021

Before I investigate it deeper I wanted to sync if anything has changed with the CDN version?

Could you provide more details or a repro? @PolygonalSun is going to take a look, if there is a regression we will definitely fix it ASAP.

There were a couple of changes that have been made to how we’re handling pointer events, specifically that we’ve changed the how some button presses are caught and remove the “FakeFire” type of event from the pointermove event listener. Any information on what issues/errors you’re seeing on your tests and what version of Babylon.js you’re using (eg. 5.0 alpha 60) would help us to better understand what’s happening.

I am running the tests against 4.2 and 5.0. I will spent some time trying to understand what is happening then

Last time they passed was Build #1244 (Nov 7, 2021 4:09:39 PM)

The tests fail only on a specific machine where we execute central builds. They don’t fail locally. I guess it is not part of babylon but probably part of the environment. This is what has changed there (leaving it for the record if anyone faces this)

You have quite a few 404 and 500 results in your log maybe your server is not reachable from this box

Is that the entire log, or just the error log?
How did babylon initialize? what version of the engine is being used? webgl1/2?

Oh, and - does it still work with an older version of babylon on this hardware?

It stopped. It was failing between 08 and 09 of November and it just stopped. What I did was returning xvfb to the previous version

2021-11-08 23:00:34 upgrade xvfb:amd64 2:1.20.9-2ubuntu1.2~20.04.2 2:1.20.11-1ubuntu1~20.04.2

Not sure how did this impacts anything, but it just stopped and has not failed since then. We are running it every day.

@RaananW

This is just the error log. The entire log has a lot of other things in it from the specs that are messages.

How did babylon initialize? what version of the engine is being used? webgl1/2?
we are rotating between cdn and preview versions.

does it still work with an older version of babylon on this hardware?
I am not sure how could I run it against older versions. We are running agains cdn.babylonjs.com and preview.babylonjs.com

It is possible.
