admin.firestore is not a function

[rndlaine]

Got this error when requiring firetore-seed. Could it be that firebase-admin is outdated?

"firebase": "^7.15.4",
"firebase-admin": "^8.11.0",
"firebase-functions": "^3.7.0",
"firebase-tools": "^8.4.2",
"firestore-seed": "0.0.11",

/Users/renaud/Code/yasx/functions/node_modules/firestore-seed/dist/index.js:177
        var firestore = admin.firestore();
                              ^
