My cronjob fails to run my Civimail queue. What am I missing here?

Question

This invocation now returns a result code of 0.
And still I see no evidence that it ran my civimail,
in the browser UI, at /civicrm/mailing/browse/unscheduled,
nor in the logs at /civicrm/admin/joblog, nor in my inbox.

I've been struggling with this issue for a moment now.
Sorting through these issues, to get to this point is documented here:
CiviMail cron job unable to find: civicrm.config.php, built with: roundearth/drupal-civicrm-project

/usr/bin/nice -n19 /usr/bin/php \
    -d require /opt/local/my_client/drupal/vendor/autoload.php \
    /opt/local/my_client/drupal/vendor/civicrm/cv/bin/cv api job.execute \
    --cwd=/opt/local/my_client/drupal --user=mailprocess

My script now reads:

#!/bin/bash
set -x

CMD=$1
CWD='/opt/local/my_client/drupal'
CV="${CWD}/vendor/civicrm/cv/bin/cv"
CIVIMAIL_USER='mailprocess'
requirements="-d require ${CWD}/vendor/autoload.php"
PHP="/usr/bin/nice -n19 /usr/bin/php"
ARGS="--cwd=${CWD} --user=${CIVIMAIL_USER}"

cd ${CWD}; ${PHP} ${requirements} ${CV} api job.execute ${ARGS}
exit "$?"

Your script is nicely designed for running the civi cron using "cv", quietly in the background. But you want to run it w/ noise so you can debug it.

To start, try running it manually without the last line and see if you get anything. The main script here is "cv" (run as a php script) and the other bits are making sure cv runs with the right arguments. If it's quitting silently, try something simpler, like seeing if you can actually run php and then if you can run cv via php with a simpler argument like "vars:show".

Documentation of cv is here: https://github.com/civicrm/cv
