D3 heat map Beta tester

I’ve been working on the D3 heat map for the last couple of days. I’ve managed to pass all the test but one.

The x-axis alignment with the years is not passing. It is working though, wherever there’s a tick, it matches with the rects above it.

I have tried everything from changing the widths of the table and the bars, to using date objects, to specify the range for the ticks.

The tester though only says “expected false to be true”. Doe anyone one what is it testing for exactly so I can work with it because right now I’m just blindly trying to make it work.
