PHP Fatal error: Uncaught Error: Class “DynamicHeartbeat\WP_CLI” not found

I did the following command:

user@server:/path/to/site# /usr/local/bin/wp --allow-root post list --post_type=post --format=count

This was the result:

PHP Fatal error: Uncaught Error: Class "DynamicHeartbeat\WP_CLI" not found in /path/to/plugins/dynamic-front-end-heartbeat-control/defibrillator/cli-helper.php:118

I tried uninstalling and reinstalling the plugin, same result.

To see if there might be a quick fix on my end, I ran the whole situation through Claude, including giving it the cli-helper.php file, and it said:

“The issue is that you’re in the DynamicHeartbeat namespace, but WP_CLI is a global class. When PHP tries to find WP_CLI within the DynamicHeartbeat namespace, it’s actually looking for DynamicHeartbeat\WP_CLI, which doesn’t exist. Contact the plugin author with the specific fix. Tell them they need to add use WP_CLI; after their namespace declaration, or reference \WP_CLI (with leading backslash) instead of WP_CLI in their code.”

I don’t know if that’s accurate or not, but maybe that helps.

For now I’ve had to uninstall the plugin to run the CLI command, I couldn’t find any other workaround.
