Tell us what’s happening:

I’ve tried several options and none of them is working, I need to slice the bios that are longer than 50 characters and not able to pass the test.

Your code so far

${bio.length > 50 ? `${bio.slice(0, 49)}...` : bio}

Hey @fernandoguevara.sv,

There is definitely a bug in the challenge parser for this. But, you do still need to get the first 50 characters, not the first 49 characters.

Once you change that, so you can move on, change the template literal string below to put bio.slice and the ellipsis ... together using string concatenation and single or double quotes. It doesn’t like having another template literal string inside of the template literal string, although that is perfectly valid JavaScript.

EDIT: There is an already a submitted issue and pull request to fix the issue. It looks like it just hasn’t been merged yet.
