Wp-cli on lightsail. undefined index

Hi All,
I have installed wp-cli. The command “wp” works but any subcommand indicates that “This does not seem to be a wordpress install”

Running: wp –path=/opt/bitnami/apps/wordpress/htdocs info returns

PHP Notice: Undefined index: HTTP_HOST in phar:///usr/local/bin/wp/php/WP_CLI/Runner.php(982) : eval()’d code on line 90
PHP Notice: Undefined index: HTTP_HOST in phar:///usr/local/bin/wp/php/WP_CLI/Runner.php(982) : eval()’d code on line 91
PHP Fatal error: Uncaught Error: Call to undefined function add_filter() in phar:///usr/local/bin/wp/php/WP_CLI/Runner.php(982) : eval()’d code:110

I suspect that the lightsail specific install of php and wordpress may be the issue.

I would appreciate your help to resolve.
