Hello, as stated above this PR is the updated version of #1383. Sadly it seems like the helm chart is still outdated and I do not see any open PRs addressing that. Can you tell me what the status is there?

@julianocosta89, thanks a lot for the info, as soon as this PR is merged I will make the changes to the helm chart.

Also, do you perchance know why the tracetesting check is failing? I am asking because I made sure to check that it passes locally (see image). Would appreciate your insights.

Testing out your PR, I did see the failing test.
It seems that the folks from TraceTest changed the name of the trigger and the test wasn't found.
Not related to your PR, but since the update of traceTest you are the first one to touch checkoutService.

I added the fix to your PR, hope you don't mind.
