las variables de datos de vue no están definidas en el método

Estoy trabajando con Vue y creando un juego y cuando obtengo los datos para dicho juego, algunas variables que he definido en los datos se devuelven sin definir. Aquí está el código:

 data() { return { receivedGame: undefined, allSteps: [], }
 methods: { async gameData() { const response = await fetch(`...`); const responseData = await response.json(); this.receivedGame = responseData.steps; //returns correct data responseData.steps.map((step) => { this.allSteps.push({ //returns error, allSteps is undefined type: step.type, }); }); } }

El gancho de data debe ser una función que devuelva un objeto. ¡Aquí no devuelves nada!

 data() { return { receivedGame: undefined, allSteps: [], } }
