This error is caused by using a version of the ArduinoJson library that is not compatible with this library. The solution is to roll back to the newest compatible version of ArduinoJson:

  1. Sketch > Include Library > Manage Libraries...
  2. Wait for download to finish.
  3. In the "Filter your search..." box, type: arduinojson
  4. Click on "ArduinoJson by Benoit Blanchon.
  5. From the dropdown version menu, select "Version 5.13.4"
  6. Click "Update".
  7. Wait for the update to finish.
  8. Click "Close".

After that, the code should compile.

More information, as well as a guide to updating the library to the ArduinoJson 6.x.x API:

Thank you, got past that, but will not compile to any boards listed. It see the boards and has port, but no compile.
