Graphql apollo playground - how to add array of strings - mongodb

Question

tldr: How do I write a mutation in GraphQL playground to add an array of strings when creating a new record in the database
I'm using a MongoDB database for an application. I always have trouble finding documentation for how to write queries and mutations in GraphQL apollo playground. In this example, let's take an example of an athlete. An athlete can win many awards. The awards are just an array of strings. I will use a simple model as an example...
const playerSchema = new Schema({
playerName: {
type: String,
required: true,
},
awards: [{
type: String,
}]
})
const Player = model('Player', playerSchema)
module.exports = Player;
Here is my typeDef for this model with Queries and Mutations
const typeDefs = gql`
type Player{
playerName: String!
awards: [String]
}
type Query {
players: [Player!]
}
type typeDefs {
addPlayer:(playerName: String!, awards:[String]
}
}`;
module.exports = typeDefs;
Here is my resolvers for this model
const resolvers = {
Query: {
players: async () => {
return await Player.find(populate('player');
}
Mutation: {
addPlayer: async( parent, {playerName, awards}) => {
return await Player.create({playerName, awards})
}
}
module.exports = resolvers;
Now, I start the server and go to GraphQL playground in the browser. I cannot add an array of strings for the awards. How do I write this query in GraphQL playground? Here is an example of my best attempt:
mutation addPlayer($playerName: String!, $awards:[String]){
addPlayer(playerName:$playerName, awards:$awards){
playerName
awards
}
}
and finally my query variables for this mutation
{
"playerName": "Michael Jordan",
"awards": ["Most Valuable Player", "Rookie of the Year", "Scoring Champion"]
}
If I run a query in GraphQL to see what players exist in the database:
query players{
players{
playerName
awards
}
}
This is the results. Why is the 'awards' array empty??
{
"data": {
"players": [
{
"playerName": "Michael Jordan",
"awards": [], //EMPTY ARRAY HERE, WHY?
}
]
}
}
