Credential issues after purchase confirmation

Hello. I'm able to list products and make purchases but after making a purchase I get this error.

I read on the documentation that if you get this error after purchasing I need to make sure the shared secret is correct. So I double checked but got the same result, then I regenerated another shared secret but I'm still getting the same error message:

There was a credentials issue. Check the underlying error for more details. Invalid API Key.

If I try to restore my purchases I get the same error. 

Hopefully somebody can help me with this issue.

This is the code I'm using to restore:

const restore = async () => {
    try {
      await Purchases.restorePurchases();
      const purchaserInfo = await Purchases.getCustomerInfo();
      console.log(purchaserInfo)
      setIsSubscribed(typeof customerInfo.entitlements.activeiproductIdentifier] !== "undefined");
    } catch (error) {
      console.error(error);
    }
  };

This is the code I'm using to purchase:

const purchase = async () => {
    try {
        const buy = await Purchases.purchaseProduct(productIdentifier)
      const purchaserInfo = await Purchases.getCustomerInfo();
      console.log('BUY: ',buy);
    } catch (error) {
      console.error(error);
    }
  };

Thanks
