@dinhxuanvu, could you please give to us a hand on in this one?

I'm a bit confused here. I only see a yaml file. Where are the codes?

Hi @dinhxuanvu,

Sorry, I did not push the full commit. All done now.
Could you please help us get this small fix/nit get merged?

[dinhxuanvu]

@camilamacedo86 No worries. Can you do me a favor and strip out anything that is not needed in the CSV yaml to reduce its size if possible?

[camilamacedo86]

@dinhxuanvu, done 👍
