node.js - Key Pair wont get associated with the EC2 instance -

I wrote a code that creates KeyPair (the MakeOpair function), creates an example (run instance) and then assign it Tries to do key combinations (for example) with example

The parameters that I have passed for the run instruction:

  var params = {ImageId: 'myami', Instance type: 'T1' micro ', minimum number : 1, MaxCount: 1};  

The parameters that I passed for the description:

  var p = {InstanceIds: [instanceId], filter: [{name: 'key- Description The Instance function gives me:  
  {reservation: []}  
  [Mykey]}]}  P> And when I check in the console, it shows "Example is not associated with a key pair. This example is not associated with any key pair. Without a key pair, you can use a valid username and password combination Tax Area must enter this instance. " . 
 
 What am I doing wrong? Am I not using the correct (/ implementation) functions? 
 

You can not be allocated RunInstances, description of the description only describes your current examples Will do
