I've been struggling a lot with Drush 9 sql:sync the past few months. I've gotten it to work a few times, but I've been stumped by this most recent problem:

$ drush sql:sync @prodv2 @local --debug Using the Drush script found at /Applications/MAMP/htdocs/ianmoffitt/vendor/drush/drush/drush using proc_open [preflight] Config paths: /Applications/MAMP/htdocs/ianmoffitt/vendor/drush/drush/drush.yml,/Applications/MAMP/htdocs/ianmoffitt/drush/drush.yml [preflight] Alias paths: /Applications/MAMP/htdocs/ianmoffitt/web/drush/sites,/Applications/MAMP/htdocs/ianmoffitt/drush/sites [preflight] Commandfile search paths: /Applications/MAMP/htdocs/ianmoffitt/vendor/drush/drush/src,/Applications/MAMP/htdocs/ianmoffitt/drush [bootstrap] Bootstrap to none [0.13 sec, 8.14 MB] [bootstrap] Drush bootstrap phase 0 [0.13 sec, 8.14 MB] [bootstrap] Try to validate bootstrap phase 0 [0.13 sec, 8.14 MB] [error] The "destination" argument does not exist. [0.13 sec, 8.19 MB]

Can't find anything online towards this specific error message. Not sure what I'm missing or what to even check.

Again, this command worked about a week or so ago. All I've done since then is run composer update. Did something change recently?

Using Drush 9.3.0.


Definitely a problem with Drush 9.3.0, revert back to Drush 9.2.3 with composer require drush/drush:9.2.3 fixed it for me

  • Please post output of drush sa for bth aliases, drush st on both sides of the sql:sync, and full --debug for the sql:sync. The output above looks abridged to me. Jun 6 '18 at 10:05

Just for the record - in my case, given "destination" argument was coming from an outdated custom Policy command I got when I was setting up the project - https://github.com/drupal-composer/drupal-project/blob/8.x/drush/Commands/PolicyCommands.php

It should be "target" instead and the current state of https://github.com/drupal-composer/drupal-project reflects that change.
