@johnchen-k thanks for working on this. If you could look into the test failures that would be great. Thanks.

Looking at the errors, they're all similar to this:

expected error location row 4, got 3

So I guess the "new" marshaller changes the order of how things are printed?
Did you decide to give up on thos @johnchen-k? Let me know if you want me to pick it up.

[johnchen-k]

Yes, the error of new marshaller dose not contain line number. Parse uses regex to get the line number from error of marshaller. So It always uses the default row.

I can not focus on this issue this week and don't want to be the bottleneck, so I close it. It would be great if you can pick it up.

BTW: the new marshaller returns float64 for number not int, like "a": 1,. It can be fixed by changing to ""a": float64(1),". But I'm not sure if there are any other effects. Could you help to have a look?

[anderseknert]

Thanks for that great investigation! It sounds more complex than I initially thought, so I don't think I'll be able to pick this up until possibly after KubeCon. If anyone else feels inclined, feel free to take a stab at it!
