I get that error on the console whenever I run this code:
const response = JSON.parse(`{"version":1,"tests":[],"hits":[{"title":"Answer one of our market research surveys (~ 2 to 12 minutes + 1-2 minutes for demographics)","hit_set_id":"36R3RQSDQUGLBEZ545II11576K307C","requester_name":"UXreviewer.io ResearchLab","requester_id":"A1HXBVQANVSV6H","reward":"0.26","description":"Give us your opinion about usability, products, and marketing.

`);
for (let i = 0; i < response.hits.length; i++) {
console.log(response.hits[i]);
console.log(response.hits[i].hit_set_id);
const hitId = response.hits[i].hit_set_id.toLowercase();
const title = response.hits[i].title.toLowercase();
const requesterName = response.hits[i].requester_name.toLowercase();
const requesterId = response.hits[i].requester_id.toLowercase();
}As you can tell from the response object, response.hits[i].hit_set_id is a string, yet when I try to call toLowerCase() on it I get that exception. I honestly have no idea what's happening.
.toLowerCase() is case sensitive.
you spelled toLowerCase wrong in multiple places.
for (let i = 0; i < response.hits.length; i++) {
console.log(response.hits[i]);
console.log(response.hits[i].hit_set_id);
const hitId = response.hits[i].hit_set_id.toLowerCase();
const title = response.hits[i].title.toLowerCase();
const requesterName = response.hits[i].requester_name.toLowerCase();
const requesterId = response.hits[i].requester_id.toLowerCase();
}
