Error is thrown when trying to run the connector

I started seeing some weird errors. The following is (truncated) exec logs.

I am not sure where exactly the problem is. I was trying to change the configuration to bare minimum, then i tried to copy the configuration from the readme file but still no luck. Regular karma tests are executed locally and on Travis. The errors start only when trying to run SL tests.
I am hoping for a help with solving this.

Hi @jarrodek

It looks like the driver is closed somewhere, based on this part of the log UncaughtException:: Cannot read property 'results' of undefined
Can you provide a reproducible example so we can debug this?

[jarrodek]

@TwoPlusTwoOne could you please reproduce this in a separate repo? Please, create a new repo in our org with this issue.

Stumpled upon the same thing, I just took https://github.com/axios/axios and upgraded all deps to:

if you run npm run test afterwards, you will get the same error.

Thanks @simllll

Will take a look at it tomorrow and let you know

@simllll

I cloned the project, updated the dependencies as mentioned and adjust the webpack.config.js and got the following as seen below.
I only got some dependency errors, but for the rest it worked. What are you seeing then?

 npm run test -- --force

Strange, what I did besides the package.json was removing uglify from webpack config and and rmeove the comment /global toString:true/ from utils.js. I guess you did probabaly the same, what system are you running on?
Mine:
node v15.2.0
Ubuntu 20.04.1 LTS
Google Chrome 85.0.4183.121
Mozilla Firefox 82.0.3

Maybe it's related with node 15? I will check now.
Update: same issue ( TypeError: Cannot read property 'results' of undefined
at SaucelabsReporter.onSpecComplete (/home/simon/Dev/other/axios/node_modules/karma-sauce-launcher/dist/reporter/reporter.js:31:35) with node 14.15.0

as a side note, not sure if relevant, but I get a warning that safari is not found (well I'm on linux ;)):

Please, set "SAFARI_BIN" env variable.

If i compare the browsers to your list, the indeed differ a lot. Could this be some hint?

Anything I can do to help tracking this down? I believe it has something todo with my environment...

Can you share a reproducible example?

@jarrodek

A fix has been released, can you please check if it works for you?

[anglinb]

@wswebcreation I bumped the karma-sauce-launcher version to 4.3.6, following your last comment. The tests are still failing but with a different error

• Travis CI Logs
• Sauce Labs Test Results

Example log output from one of the failures:

Let me know if you can find any clues, thanks!

Hi @anglinb

Strange, it looks like the Sauce Connect Tunnel is killed before your tests are finished, can you enable the Sauce Connect logs are shown here and share them?

[anglinb]

I don't have write access to the repo so would have to open another PR but the cycle time between trying a change, opening a PR, merging to master is pretty gnarly 😅 I thought I could fix it by just bumping the version but that didn't work out. Maybe the maintainers might be up for it but ya unfortunately PRs don't run with Sauce creds until merged.

It was literally just bugging me all the build indicators were red haha
