Now, I’m trying Apollo Odyssey and have one question for it.
At 1:43 of this video in ODYSSEY, the screen shows the json response.
However, my screen shows the following message, “Error! Unexpected token < in JSON at position 0”, instead of the json response.
You can see the string of “undefined” when I debug in the client/src/pages/tracks.js.
Why does the Catstronau in my localhost indicate “Error! Unexpected token < in JSON at position 0”, although I do programming following the video and the document of ODYSSEY - LIFT-OFF I: BASICS.
I would like you to tell me how to solve this error.
