Type issue on Keep Alive artisan command

[johntrickett86]

When running the artisan command:

php artisan xero:keep-alive

the following Type Error is received:

Carbon\Carbon::rawAddUnit(): Argument #3 ($value) must be of type int|float, string given, called in /vendor/nesbot/carbon/src/Carbon/Traits/Units.php on line 356
