Azure Eventhub High Request Volume

I have an Event hub that is receiving about 50 requests a minute and I am not sure what from. They aren't messages because the messages and throughput are all normal. I have sent some requests to logs and the Caller_s field is always Resource Provider. I am using the JavaScript SDK to connect to it but was careful to make sure I am reusing the same client and not spawning a bunch (see code below).


import config from "@/config";
import { EventHubProducerClient } from "@azure/event-hubs";

let eventHubConnection: EventHubProducerClient;

export async function getEventHubConnection(): Promise<EventHubProducerClient> {
  if (eventHubConnection) {
    console.log("Connection to EventHub already established");
    return eventHubConnection;
  }
  try {
    eventHubConnection = new EventHubProducerClient(
      config.env.EVENTHUB_CONNECTION_STRING,
      config.env.EVENTHUB_NAME,
      {
        userAgent: "inviza-api/0.1.0",
      }
    );
  } catch (error) {
    console.error("Error establishing producer client for cloud", error);
    throw error;
  }

  console.log("Connection to EventHub established");
  return eventHubConnection;
}

export async function closeEventHubConnection(): Promise<void> {
  if (!eventHubConnection) {
    console.log("No EventHub connection to close");
    return;
  }
  try {
    await eventHubConnection.close();
    console.log("Eventhub connection closed");
    return;
  } catch (error) {
    console.error("Error closing EventHub connection", error);
  }
}

export default getEventHubConnection;

Any suggestions on where to look or what might be wrong would be a great help.
