Invalid path alias: @ error

I have a site running Craft 3.6.11.1. I’ve been working on it for a while, have multi environment config set up and everything working great. I have recently installed and uninstalled quite a few plugins. I’m not sure exactly when something went wrong but now in terminal when I do ./craft I get:

Exception 'yiibaseInvalidArgumentException' with message 'Invalid path alias: @'

in /srv/users/serverpilot/apps/dev-odette-craft/vendor/yiisoft/yii2/BaseYii.php:154

Any ideas on how to fix this would be much appreciated.
