Hi @woblerr, when bumping the go version to 1.2.5 in PR #99 the end-to-end test failed, I need your help. When you are available, could you please take a look at it? Thanks!

[woblerr]

I have made several modifications in PR #99. The tests are now passed. But an additional review of my changes is required.
