Getting error message "Invalid request: {0}"

[cis-pjain]

Hello,

I am getting error response {"responseEnvelope"=>{"timestamp"=>"2014-01-13T03:36:10.038-08:00", "ack"=>"Failure", "correlationId"=>"a668cb42ba8d5", "build"=>"7935900"}, "error"=>[{"errorId"=>"580001", "domain"=>"PLATFORM", "subdomain"=>"Application", "severity"=>"Error", "category"=>"Application", "message"=>"Invalid request: {0}"}]}

I have run the following code

data = {
  "returnUrl" => root_url, 
  "requestEnvelope" => {"errorLanguage" => "en_US"},
  "currencyCode"=>"USD",  
  "receiverList"=> { "receiver"=>[{ "email"=>self.paypal_email, "amount"=> self.amount}]},
  "cancelUrl"=>root_url,
  "actionType"=>"CREATE",
  "ipnNotificationUrl"=>root_url,
  "startingDate" => DateTime.now
}
preapproval = pay_request.preapproval(data)
pay_response = pay_request.pay(data)
self.pay_key = pay_response["payKey"]
self.paypal_status = "Payed"
execute_payment = pay_request.execute_payment(pay_response["payKey"])

Please help me out from this...

Thanks in advance

I had the same issue. For me, I didn't submit the amount as a String (like "19.99"). Just call data.to_json and see if everything seems valid.
Hope that helped.
