Cannot run 'composer update'

Hi,
I’m trying to run ‘composer update’ but I’m getting the following error:
Can’t resolve placeholder {%WP_PLUGIN_GF_KEY}. Environment variable ‘WP_PLUGIN_GF_KEY’ is not set.

If i look in the ‘group_vars/all/main.yml’ it is listed under ‘vault_wordpress_env_default’.
What am i missing?

I did run “trellis dotenv” also to make sure the plugin keys is set.
