Hi,  
I am new to airvantage and exploring the various features available in airvantage.

My Initial POC is to create a application Model and release it to Airvantage, followed by writing an MQTT scala app to post the data from device/my mac to airvantage.

I am facing an issue in uploading/releasing the application model using develop =\> my apps =\> release new application, and have followed the steps provided in the below link

[source.sierrawireless.com/airva … ion\_howto/](https://source.sierrawireless.com/airvantage/av/howto/cloud/application_howto/)

Application Model:::

\<?xml version="1.0" encoding="ISO-8859-1"?\>

\<app:application  
xmlns:app=“[http://www.sierrawireless.com/airvantage/application/1.0](http://www.sierrawireless.com/airvantage/application/1.0)”  
type=“newbeeonairvantage”  
name=“NewToAirvantage”  
revision=“1.0”\>

I have saved the above xml as devicedata.app and zipped when i release the application am getting “several .app files exist and expected only one”, though i have one one . please advise what could be the cause for this issue.

Anything to do with permission of my account?

Thanks  
Thani

Hi ,

Might be the .zip file which you are uploading is not a valid one.

If you can share the .zip file with us , we can also test it from our end.

Thanks & Regards,
