I am very new to Arduino. I am trying the 2nd project in on-line tutorial one gets when registering IoT kit. Project is called "Graphing Data in the Cloud".
My sketch compiles ok, and it loads ok. The display on MKR IoT Carrier first seems to indicate it found the WiFi SSID, but then continues to say "Waiting for Connection....
I have entered the SSID and Password for my WiFi network into the SECRET tab on the on-line editor: Arduino Cloud. I have reviewed many of the postings that seem to be related to this problem, but have not found the solution (but i'll continue to read more of them).
Hardware:
MKR WIFI 1010 with MKR IoT Carrier; laptop running Google Chrome
Here are error messages from Monitor:

Here is the sketch, (I have tried to use the code formatting, but not sure if i have that right.)
// BSEC Software Library - Version: 1.6.1480

Arduino IoT Cloud Variables description
The following variables are automatically generated and updated when changes are made to the Thing
float humidity;
float temperature;
Variables which are marked as READ/WRITE in the Cloud Thing will also have functions
which are called when their values are changed from the Dashboard.
These functions are generated with the Thing and added at the end of this sketch.

#include "thingProperties.h"
#include <Arduino_MKRIoTCarrier.h>
MKRIoTCarrier carrier;
void setup() {
// Initialize serial and wait for port to open:
Serial.begin(9600);
// This delay gives the chance to wait for a Serial Monitor without blocking if none is found
delay(1500);
// Defined in thingProperties.h

ArduinoCloud.printDebugInfo();
//Wait to get cloud connection to init the carrier
while (ArduinoCloud.connected() != 1) {
ArduinoCloud.update();
carrier.display.setTextSize(3);

}
