MKR WiFi 1010 not loading program

I've been experimenting with my new MKR WiFi 1010 and Temboo to send emails using a google account.
During the process I must have done something wrong because I got back a lot af red characters in the Desktop IDE feedback area but no feedback from the sensors and time in the Serial Monitor window.
Computer Is MacBook Pro with OS 10.13.6
Arduino IDE is 1.8.9

This is what I get back when I try to upload my sketch:

Sketch uses 37860 bytes (14%) of program storage space. Maximum is 262144 bytes.

Any suggestions ?

the upload was successful. it is possible that the port number changed after upload

This is embarrassing !
Everything is working.
I did not see that red character feedback before so I assumed something was wrong and I did not get anything on the serial monitor either.
I tested with the Examples, Basic, Blink Sketch and that worked fine.
Also the Examples, Basics, DigitalReadSerial was OK. I got Serial monitor output
And then I notices that the power wire to the Breadboard was disconnected.

So I'm back on track for my testing.
Still wondering why I get all that red feedback after the Upload?

The Arduino IDE's console windows colors everything that's printed to stdout white and everything that's printed to stderr red. Unfortunately, the upload tool prints its non-error output to stderr, which results in the unexpected coloration. There has been some talk about fixing this, but it can't really be done in an elegant way.

Note that you will only get this output in the console window when File > Preferences > Show verbose output during: upload is checked. If you previously had that option unchecked, it could have been the cause of your confusion. I recommend always leaving that option enabled, since it's very useful to get some indication of the progress of the upload.

thanks!

You're welcome. I'm glad if I was able to be of assistance. Enjoy!
