Issue of sendNotification with REST api to KAA

Question

According to KAA documents, send Notification to KAA with below command,

curl -v -S -u devuser:devuser123 -F'notification={"applicationId":"3","schemaId":"20","topicId:"1","type":"USER"};type=application/json' -F file=@/home/richard/notification.json "http://192.168.30.27:8080/kaaAdmin/rest/api/sendNotification"

I'm sure that the IP address of KAA server and notification settings are right. But get below errors,

HTTP/1.1 100 Continue HTTP/1.1 400 Bad Request

Any guys meet the same issue and could you please give some clue?

Answer 1

Response Messages: 400 The specified notification is not valid

I think you need to check your message's style for notification.json.

My message style is { "Message": "Hello world!"} and .avsc file is :

{
  "type" : "record",
  "name" : "Message",
  "namespace" : "hello.world.com",
  "fields" : [ {
    "name" : "Message",
    "type" : {
      "type" : "string",
      "avro.java.string" : "String"
    },
    "displayName" : "",
    "displayPrompt" : ""
  } ],
  "version" : 1,
  "dependencies" : [ ],
  "displayName" : "Message",
  "description" : ""
}

Answer 2

maybe in your notification body schemas any field is optional. you need change your json file. for example:

{"notifId" : "16243", "notifInfo": {"string":"this is info"}, "notifType" : 90, "notifPayload" : "this is payload" }

notifInfo is optional
