I received an email with a link to this and quickly added a .bitbucket/CODEOWNERS file to my project but when I created a pull request, the Reviewers were never populated. I made several pull requests after checking in the required CODEOWNERS file, and no dice.
My file only has one line in it. For the sake of this example, let's say my workspace slug is spider-man. I also have a group called javascripters with 3 members associated to it. This is my file:
* @ spider-man/javascripters:all
In the snippet above, since the formatting in this text editor does too much magic, I had to add a space after the symbol that I don't actually have in my real file.
