PayPal Incoming JSON request does not map to API

Question

I'm trying to create payment with PayPal and I get errors.

Errors:

400{"name":"MALFORMED_REQUEST","message":"Incoming JSON request does not map to API request","information_link":"https://developer.paypal.com/webapps/developer/docs/api/#MALFORMED_REQUEST","debug_id":"f79dc9a739991"}exception 'PayPal\Exception\PayPalConnectionException' with message 'Got Http response code 400 when accessing https://api.sandbox.paypal.com/v1/payments/payment.' in /home/nork/domains/nork.lt/public_html/cms/xxx/system/payments/PayPal-PHP-SDK/paypal/rest-api-sdk-php/lib/PayPal/Core/PayPalHttpConnection.php:202 Stack trace: #0 /home/nork/domains/nork.lt/public_html/cms/xxx/system/payments/PayPal-PHP-SDK/paypal/rest-api-sdk-php/lib/PayPal/Transport/PayPalRestCall.php(73): PayPal\Core\PayPalHttpConnection->execute('{"intent":"sale...') #1 /home/nork/domains/nork.lt/public_html/cms/xxx/system/payments/PayPal-PHP-SDK/paypal/rest-api-sdk-php/lib/PayPal/Common/PayPalResourceModel.php(104): PayPal\Transport\PayPalRestCall->execute(Array, '/v1/payments/pa...', 'POST', '{"intent":"sale...', NULL) #2 /home/nork/domains/nork.lt/public_html/cms/xxx/system/payments/PayPal-PHP-SDK/paypal/rest-api-sdk-php/lib/PayPal/Api/Payment.php(577): PayPal\Common\PayPalResourceModel::executeCall('/v1/payments/pa...', 'POST', '{"intent":"sale...', NULL, Object(PayPal\Rest\ApiContext), NULL) #3 /home/nork/domains/nork.lt/public_html/cms/xxx/checkout.php(73): PayPal\Api\Payment->create(Object(PayPal\Rest\ApiContext)) #4 {main}

The answer appears to be that you are not sending sufficient request values:

{"intent":"sale...', NULL)

Note the null. In order to see your error dump in more details, you can do tweak the var_dump complexity:

ini_set('xdebug.var_display_max_depth', 10);
ini_set('xdebug.var_display_max_children', 256);
ini_set('xdebug.var_display_max_data', 1024);

Then you will see the full JSON and can figure out what was missing or malformed.
