Help with wp cli and cron

Hi,

I’m wondering if anyone can help with this issue. A shared host provides wp cli pre installed. This seems to work perfectly from command line, but not when installed and run from cron.

examples of commands used ( which work in shell )

cd /home/account/public_html;/usr/local/bin/wp --debug --info > /home/logs/wpcron.log 2>&1

source /home/.bash_profile;cd /home/account/public_html;/usr/local/bin/wp --debug --info > /home/logs/wpcron.log 2>&1

PATH = $PATH:/usr/local/bin;export PATH;cd /home/account/public_html;/wp --debug --info > /home/logs/wpcron.log 2>&1

normal debug and info comes out on command line

but when trigged through cron I get

PHP Notice:  Undefined index: argv in phar:///usr/local/bin/wp/vendor/wp-cli/wp-cli/php/WP_CLI/Runner.php on line 905

which are warnings and notices ( not fatal )
but zero output

I have googled quite extensively and have not come across anything similar

Any pointers?
