I’m trying to get the ChirpStack API working using node.js. I’m specifically trying to perform API actions on the public Helium LNS managed by Meteoscientific. I’m ending up getting 400-not-found errors when I see gRPC requests to the same URLs work in the browser.
Here’s the code, slightly amended from the sample to use the same API call as I see on one of the Web UI pages:
import grpc from "@grpc/grpc-js"
import device_grpc from "@chirpstack/chirpstack-api/api/device_grpc_pb.js"
import device_pb from "@chirpstack/chirpstack-api/api/device_pb.js"
// This must point to the ChirpStack API interface.
const server = "console.meteoscientific.com:443";
// The API token (can be obtained through the ChirpStack web-interface).
const apiToken = "eyJ0eX...PSFI"
// Create the client for the DeviceService.
const deviceService = new device_grpc.DeviceServiceClient(
server,
grpc.credentials.createSsl(),
);
// Create the Metadata object.
const metadata = new grpc.Metadata();
metadata.set("authorization", "Bearer " + apiToken);
// ListDevices
const ldreq = new device_pb.ListDevicesRequest(100, 0)
deviceService.list(ldreq, metadata, (err, resp) => {
if (err !== null) {
console.log(err);
return;
}
console.log("Got device list: " + resp.total_count);
});
When I run this with verbose debug I see:
D 2025-02-24T05:51:24.278Z | v1.12.6 281466 | resolving_call | [0] ended with status: code=13 details="Received HTTP status code 400"
Error: 13 INTERNAL: Received HTTP status code 400
The request goes to /api.DeviceService/List:

Interestingly, in the browser when I look at the device list for one of my applications I see:
So hostname, port, and URI are correct. If auth was wrong I’d expect to seeswomething better than 400 but I don’t know enough about ChirpStack’s API implementation.
Here’s the full debug log:
