Error key=value uploading

I think the easiest thing to do will be to remove and then reinstall the problematic library. Please try this:

  1. Open this folder in Windows File Explorer:
    C:\Users\Owen\Documents\Arduino\libraries
    
  2. Delete the folder named Arduino_Cloud_Provider_Examples.
    Please be very careful when deleting things from your computer. When in doubt, back up!
  3. Select Sketch > Include Library > Manage Libraries... from the Arduino IDE menus.
  4. Wait for the update to finish.
  5. In the "Filter your search" field, type "Arduino Cloud Provider Examples".
  6. Press Enter.
  7. Scroll down through the list of libraries until you see "Arduino Cloud Provider Examples by Arduino". Click on it.
  8. Click the Install button.
  9. Wait for the installation to finish.
  10. Click the Close button.

Now try compiling your sketch again. Hopefully this time you will have a valid installation of the "Arduino Cloud Provider Examples" library.
