In app billing v3 - why I get DEVELOPER_ERROR when calling queryPurchases(skuID)?

I implemented inapp billing (subscriptions) and everything works properly - I am able to subscribe, I acknowledge subscription, and billing flow ends succesfully with OK status.

However, at start of my app I am performing check (from Google Play cache) whether I already made purchases - and I always get DEVELOPER_ERROR.

This is my code:

public void checkIfPurchased() {
        billingClient.startConnection(new BillingClientStateListener() {
            @Override
            public void onBillingSetupFinished(BillingResult billingResult) {
                if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK) {
                        Purchase.PurchasesResult alreadyPurchasedResult = billingClient.queryPurchases(SKU_ID);
                        List<Purchase> alreadyPurchased = alreadyPurchasedResult.getPurchasesList();
                        ...
                        // alreadyPurchasedResult = 5 = DEVELOPER_ERROR
                }
            }
    }

Why this happens?

The method queryPurchases accepts as parameter either BillingClient.SkuType.INAPP or BillingClient.SkuType.SUBS as stated in the documentation.

In your example it looks like you put the SKU ID of your subscription product.
