mdb-theme not being recognized

Hello! I'm currently working with an older angular application that is running MDB #1.0.0

"mdb-angular-ui-kit": "git+https://oauth2:TOKEN@git.mdbootstrap.com/mdb/angular/mdb5/prd/mdb5-angular-ui-kit-pro-essential#1.0.0",

*Expected behavior*i'm currently getting a mixin error related to my mdb-theme in my styles.scss file. How can I fix this error?
