How do I solve JavaScript execution error in Johnny-five?

Original post: How do I fix johnny 5 installation error?

When I run my JS file I get this error:

1637373588955 Available COM3 
1637373588956 Connected COM3 
1637373592592 Repl Initialized 
>> 1637373598958 Device or Firmware Error A timeout occurred while connecting to the Board. 

Please check that you've properly flashed the board with the correct firmware.
See: https://github.com/rwaldron/johnny-five/wiki/Getting-Started#trouble-shooting

If connecting to a Leonardo or Leonardo clone, press the 'Reset' button on the board, wait approximately 11 seconds for complete reset, then run your program again. 
events.js:306
    throw err; // Unhandled 'error' event
    ^

I’ve already tried installing different Firmata software but it isn't helping. What do you think?
