My digital chest
Nobody opens
Nobody knows

Incorrect response. In your first line you have 5 syllables which is correct. You're supposed to give 7 syllables in the second line but your phrase has another 5 syllables and the last line has just 4 syllables instead of 5. You can adjust it to make it a proper haiku. Something like this below..
My digital chest............5 syllables
Nobody else opens it...7 syllables
Nobody knows it..........5 syllables
I hope this helps. I learnt it for the first time yesterday too.
My bad! Thanks for the correction.
Hope you don't mind that I edited my post with your corrections:)
