I have just started with bedrock/composer. I am using it with Local by Flywheel on a WordPress website. I have installed some plugins via composer and when I go to the website I get the fatal error:

In my “error.log” file I see  
2020/07/22 04:42:30 [error] 106#0: \*2 directory index of “/app/bedrock/” is forbidden, client: 172.17.0.1, server: , request: “GET / HTTP/1.0”, host: “rodneyco.local”

Any suggestions would be super helpful.

1. Bedrock dependencies installed (`composer install`)?+
2. Updated dotenv dependency?
