defaultValue = getFile(getCurrent.value[name])
Function getFile:
const getFile = async (id) => {
const data = store.dispatch(Actions.FILE, id).then(() => {
const data = [{ description: store.getters.currentFile.description, url: 'https://test.com/uploads/'+ store.getters.currentFile.name }]
return data
})
return data
}
If I console.log(defaultValue): I see the following output; 
But I need a array instead of this Promise thing. How to solve?
You have to use await keyword on your getFile to retrieve value front promise because your getFile returns Promise.
async function yourFunc() {
defaultValue = await getFile(getCurrent.value[name])
// do whatever you want
}
You need to use the await keyword
const getFile = async (id) => {
await store.dispatch(Actions.FILE, id);
return [{ description: store.getters.currentFile.description, url: 'https://test.com/uploads/'+ store.getters.currentFile.name }]
}
and then await the call to getFile too
defaultValue = await getFile(getCurrent.value[name])
