I apologize in advance for my English, I use google translator to write my question here
I found a code for ESP, which should track in real time what I'm currently listening to in spotify and display information about the song currently playing. In order for this code to work, I need another code that will give me a token. The trouble is that the code that should display the token for me gives the following:
..scandone
state: 0 -> 2 (b0)
.state: 2 -> 3 (0)
state: 3 -> 5 (10)
add 0
aid 2
cnt

connected with NewHome, channel 13
dhcp client start...
ip:192.168.1.176,mask:255.255.255.0,gw:192.168.1.1
.
Connected to NewHome

Could not parse error
What is the reason for this error and how to fix it?

/*******************************************************************
Get Refresh Token from spotify, this is needed for the other
examples.

Instructions:

- Put in your Wifi details, Client ID, Client secret and flash to the board
- Do one of the following

--- IF USING IP (ESP32 MDNS does not work for me)

- Get the Ip Address from the serial monitor
- Add the following to Redirect URI on your Spotify app "http://[ESP_IP]/callback/"
e.g. "http://192.168.1.20/callback/" (don't forget the last "/")
- Open browser to esp using the IP

--- IF USING MDNS

- Search for "#define USE_IP_ADDRESS" and comment it out
- Add the following to Redirect URI on your Spotify app "http://arduino.local/callback/"
(don't forget the last "/")
- Open browser to esp: http://arduino.local

-----------

- Click the link on the webpage
- The Refresh Token will be printed to screen, use this
for SPOTIFY_REFRESH_TOKEN in other examples.

To Fix a Parse Error
Update to the latest version of Android.
Check for compatibility issues, or try an older version of the app.
Enable permissions to install apps from unknown sources
Download and install your
Temporarily disable Android antivirus or other security features
Turn on USB debugging.
