wpCLI via JS API returns "Hello World!"

[eherman-godaddy]

I am trying to use wpCLI from @wp-playground/client but regardless of what command I use it always returns "Hello World!". In the examples below, the post is not created, the siteurl option is not returned nor is the plugin list displayed so it seems like wpCLI is not executing the commands properly. It appears to be working fine with the blueprint wp-cli step but not working through the @wp-playground/client wpCLI.

Code I have tried:

await wpCLI( client, { "command": "wp post create --post_title='Test post' --post_excerpt='Some content'" } );
await wpCLI( client, { "command": "wp option get siteurl" } );
await wpCLI( client, { "command": "wp plugin list" } );

Always returns:

"Hello World!"

@eherman-godaddy that's most likely because there's no /tmp/wp-cli.phar file – the code path responsible for running JSON pre-fetches it here:

wordpress-playground/packages/playground/blueprints/src/lib/compile.ts

Lines 173 to 203 in 97ecad0

	if (wpCliStepIndex !== undefined && wpCliStepIndex > -1) {
	if (blueprint.phpExtensionBundles.includes('light')) {
	blueprint.phpExtensionBundles =
	blueprint.phpExtensionBundles.filter(
	(bundle) => bundle !== 'light'
	);
	logger.warn(
	`The wpCli step used in your Blueprint requires the iconv and mbstring PHP extensions. ` +
	`However, you did not specify the kitchen-sink extension bundle. Playground will override your ` +
	`choice and load the kitchen-sink PHP extensions bundle to prevent the WP-CLI step from failing. `
	);
	}
	blueprint.steps?.splice(wpCliStepIndex, 0, {
	step: 'writeFile',
	data: {
	resource: 'url',

It would be lovely for the JavaScript step to do the same and also log a warning to communicate with the developer.
