Why is my one-time purchase app test transaction not showing?

I am using the appPurchaseOneTimeCreate mutation to create a purchase, in test mode. All works great.

Now I am using the Partner API to retrieve the transaction in order to manage the in app purchase, but nothing shows.

Is it because I am using “test” purchases or there is other reason?

Here is the graphql query that returns empty transactions:

{
transactions(types: [APP_ONE_TIME_SALE, APP_USAGE_SALE],
createdAtMin: “2021-06-01T00:00:00Z”,
createdAtMax: “2021-06-28T23:59:59Z”){
edges {
node {
id
createdAt
… on AppOneTimeSale {
chargeId
netAmount {
amount
}
app {
name
}
shop {
name
}
}
… on AppUsageSale {
chargeId
netAmount {
amount
}
app {
name
}
shop {
name
}
}
}
}
}
}
