My problem is: Cannot Create Email Channels or Send Emails

These errors are showing in the log:

You should either make it public, or stop using the container directly and use dependency injection instead. (uncaught exception) at /var/www/html/mautic/vendor/symfony/dependency-injection/Container.php line 275 while running console command `mautic:emails:send`

[2021-04-27 00:20:07] mautic.WARNING: Command `mautic:emails:send` exited with status code 1

</div>

found a workaround:

replace it with:

/var/www/html/mautic/bin/console swiftmailer:spool:send --message-limit=1 --env=prod

the above limit=1 can be changed to anything u want

Thank you. Do I do this in WINSCP? I am not sure where to make this change.
