Receiving a message result in an exception. New message structure not implemented yet?

[sandervandevelde]

I installed the integration using

npm install --save ttn-azure-iothub

And I added

const options = {};
options.ttnBroker = 'eu.thethings.network';
const bridge = new ttnazureiot.Bridge(appEUI, appAccessKey, hubName, keyName, key, options);

The bridge connects and messages are received. But upon receiving, I get this error:

predictive_maintenance_machine_42: Handling uplink
predictive_maintenance_machine_42: Could not get device: TypeError: Cannot read property 'server_time' of undefined
Error TypeError: Cannot read property 'server_time' of undefined
    at Bridge._createMessage (C:\bridge\node_modules\ttn-azure-iothub\index.js:23:30)
    at _getDevice.then.deviceInfo (C:\bridge\node_modules\ttn-azure-iothub\index.js:81:43)
    at process._tickCallback (internal/process/next_tick.js:103:7)

It seems the message is not parsed correctly. Does this have to do with changes in the message structure in production?

Regards,

Sander

Yes. This now time

It's fixed already but it requires a publish to npm (see https://github.com/TheThingsNetwork/integration-azure/blob/master/index.js#L22)

It seems the issue is not server_time or time, but the undefined metadata in:

time: message.metadata.time,

I commented out the whole line and I got no exception anymore.

Would love to see a new publish. Is downlink supported too? Current version does not seem to pass them

[johanstokking]

Should be fixed in https://github.com/TheThingsNetwork/integration-azure/commit/bc605a88f450c1417e1eaada2b333b278af880c1. Can you check?

ttn-azure-iothub@2.0.0 has been published to npm

[sandervandevelde]

Hoi Johan, it works. The telemetry is passed without any error. Thanks. But downlink doesn't seem to be supported, or does it?

[johanstokking]

Great. Let's talk in #15
