But now that you said you are working with node.js, the issue is from running node at the root level, but the program is located in the "js" directory. Start it this way instead (after fixing the space of course):
node js/promises-breakfast.js

231,060 PointsI didn't see the error you mentioned when I tried your snapshot, but I noticed how the data for one person was not available. If that's the same issue, it's because for that person (Sergey Korsakov) you get a disambiguation page instead of the info page the code is expecting. This is because there are two people with similar names in the database.
Adding code to detect and resolve a disambiguation page in a generic way would be a rather advanced challenge. But as a quick fix, you could just check for "Sergey Korsakov" and substitute "Sergey Korsakov (cosmonaut)":
btn.addEventListener('click', () => {
getJSON(astrosUrl,(json) => {
json.people.map( person => {
if (person.name == "Sergey Korsakov") // change ambiguous name to specific one
getJSON(wikiUrl + "Sergey Korsakov (cosmonaut)", generateHTML);
else
getJSON(wikiUrl + person.name, generateHTML);
});
});

4,642 PointsHi Steven, Thank you for the swift reply and sorry about the confusion. I should have described it better in my question. Currently, I have moved on from the Callbacks exercise to the Promises exercise.
The issue I was referring to is that when I tried to create a new Promise for my promises-breakfast.js file and run it on the command, it gives me a 'throw' error. Below is a new snapshot I took. Do you get the same error? https://w.trhou.se/p2ovq03goq

231,060 PointsI'm still not sure what steps to take to see this error (or what you mean by "run it on the command"), but just looking at the file I notice a stray space that is preventing the arrow operator from being recognised:
setTimeout(() = > { // operator must be =>
// ^
// stray space

4,642 PointsHi Steven, thank you for your effort to help me. Even after I remove the stray space. Basically, I'm seeing this error:
treehouse:~/workspace$ node promises-breakfast.js
module.js:550
throw err;
^
Error: Cannot find module '/home/treehouse/workspace/promises-breakfast.js'
at Function.Module._resolveFilename (module.js:548:15)
at Function.Module._load (module.js:475:25)
at Function.Module.runMain (module.js:694:10)
at startup (bootstrap_node.js:204:16)
at bootstrap_node.js:625:3
I have been stuck on this exercise for awhile. I think I will just move forward. Thank you though.

4,642 PointsThank you! It finally worked! I just didn't know there was any difference when using the server as the Workspace Preview.
