PayPal Community

Hello,   I got this problem when I use paypal express checkout on Magento 2.3. I tried to use sandbox. It seems run well. I can see the paypal login form popup and can login successfully. But after I click 'Pay' button and the popup is closed then I saw a flash error message on my Magento 2 site.           PayPal gateway has rejected request. PaymentAction of Authorization is not allowed with Unilateral and Non-Credentialed authentication (#10481: Transaction refused because of an invalid argument. See additional error messages for details).           Then I inspected the log file. I see the debug message but I have no idea what is wrong. Is this caused by Magento and/or paypal? Here is the debug message:           [2020-02-01 04:40:06] main.DEBUG: array ( 'url' => 'https://api-3t.sandbox.paypal.com/nvp', 'DoExpressCheckoutPayment' => array ( 'TOKEN' => 'EC-5TP478471D8088941', 'PAYERID' => '5YLR7L3UWZK6Y', 'PAYMENTACTION' => 'Authorization', 'AMT' => '499.00', 'CURRENCYCODE' => 'AUD', 'BUTTONSOURCE' => 'Magento_Cart_Community', 'NOTIFYURL' => 'https://xxx.com.au/paypal/ipn/', 'RETURNFMFDETAILS' => 1, 'SHIPPINGAMT' => '0.00', 'ITEMAMT' => '499.00', 'TAXAMT' => '0.00', 'L_NUMBER0' => NULL, 'L_NAME0' => '(CLEARANCE) Shoei J.O Hawker TC-1 Helmet - Red/Black', 'L_QTY0' => 1, 'L_AMT0' => '499.00', 'BUSINESS' => NULL, 'EMAIL' => 'xxx', 'FIRSTNAME' => 'First', 'LASTNAME' => 'Last', 'MIDDLENAME' => NULL, 'SALUTATION' => NULL, 'SUFFIX' => NULL, 'COUNTRYCODE' => 'AU', 'STATE' => 'NSW', 'CITY' => 'Melbourne', 'STREET' => 'Second Ave.', 'ZIP' => '3000', 'PHONENUM' => '0489 849 999', 'SHIPTOCOUNTRYCODE' => 'AU', 'SHIPTOSTATE' => 'NSW', 'SHIPTOCITY' => 'Melbourne', 'SHIPTOSTREET' => 'Second Ave.', 'SHIPTOZIP' => '3000', 'SHIPTOPHONENUM' => '0489 849 999', 'SHIPTOSTREET2' => '', 'STREET2' => '', 'SHIPTONAME' => 'First Last', 'ADDROVERRIDE' => 1, 'METHOD' => 'DoExpressCheckoutPayment', 'VERSION' => '72.0', 'USER' => '****', 'PWD' => '****', 'SIGNATURE' => '****', ), 'response' => array ( 'TOKEN' => 'EC-5TP478471D8088941', 'SUCCESSPAGEREDIRECTREQUESTED' => 'false', 'TIMESTAMP' => '2020-02-01T04:40:05Z', 'CORRELATIONID' => '577d54e9fc5fa', 'ACK' => 'Failure', 'VERSION' => '72.0', 'BUILD' => '54085969', 'L_ERRORCODE0' => '10481', 'L_SHORTMESSAGE0' => 'Transaction refused because of an invalid argument.
