TypeError: Provided value for 'message' must be of type: ServiceBusMessage in a Service Bus Queue Azure
I have the following code that connects a JSON file with an Azure Service Bus Trigger but when the trigger is activated I encounter the error TypeError: Provided value for 'message' must be of type: ServiceBusMessage
. I have found the following link that provides some sort of help but it wasn't that useful How to specify content type as application/json while sending message to azure service bus queue in node js?
module.exports = async function (context, myBlob) {
context.log("JavaScript blob trigger function processed blob \n Blob:", context.bindingData.blobTrigger, "\n Blob Size:", myBlob.length, "Bytes");
if(context.bindingData.name.indexOf("json_results") == -1){
context.log(context.bindingData.name);
return;
}
const data = JSON.parse(myBlob.toString());
context.log(data);
// service bus queue
const { ServiceBusClient } = require("@azure/service-bus");
// connection string to your Service Bus namespace
const connectionString = "Endpoint=sb://servicebus.servicebus.windows.net/;SharedAccessKeyName=RootManageSharedAccessKey;SharedAccessKey=xxxxx";
const sbClient = new ServiceBusClient(connectionString);
// name of the queue
const queueName = "service-bus-queue";
context.log("Creating queue: ", queueName);
const sender = sbClient.createSender(queueName)
try{
// Tries to send all messages in a single batch.
// Will fail if the messages cannot fit in a batch.
// await sender.sendMessages(messages);
let batch = await sender.createMessageBatch();
for (let index=0; index < data.length; index++){
// for each message in the array
// try to add the message to the batch
if (!batch.tryAddMessage(data[index])) {
// if it fails to add the message to the current batch
// send the current batch as it is full
await sender.sendMessages(batch);
// then, create a new batch
batch = await sender.createMessageBatch();
// now, add the message failed to be added to the previous batch to this batch
if (!batch.tryAddMessage(data[index])) {
// if it still can't be added to the batch, the message is probably too big to fit in a batch
throw new Error("Message too big to fit in a batch");
}
}
}
// Send the last created batch of messages to the queue
await sender.sendMessages(batch);
context.log(`Sent a batch of messages to the queue: ${queueName}`);
// Close the sender
await sender.close();
} finally {
await sbClient.close();
}
};
How do I convert this JSON file properly so it can be sent correctly to the Service Bus?
This is some sample data from the JSON file:
