azureStorageUri not created when create mobileAppContentFile in Microsoft Intune - azure-storage

Question

I want to create a mobileAppContentFile. For this I make a POST request to:
https://graph.microsoft.com/beta/deviceAppManagement/mobileApps/0122f94e-45c4-458a-a25a-c08135a036fc/microsoft.graph.windowsMobileMSI/contentVersions/1/files
with this request body:
{
"#odata.type": "#microsoft.graph.mobileAppContentFile",
"azureStorageUri": "https://NAME.blob.core.windows.net/intune/TestApp.msi",
"name": "TestApp.msi",
"isCommitted": false,
"uploadState": "azureStorageUriRequestPending"
}
I receive 201 Created response but azureStorageUri is null:
{
"#odata.context": "https://graph.microsoft.com/beta/$metadata#deviceAppManagement/mobileApps('0122f94e-45c4-458a-a25a-c08135a036fc')/microsoft.graph.windowsMobileMSI/contentVersions('1')/files/$entity",
"azureStorageUri": null,
"azureStorageUriExpirationDateTime": null,
"createdDateTime": "0001-01-01T00:00:00Z",
"id": "ca57173c-5f67-4048-90bf-3bac136de964",
"isCommitted": false,
"manifest": "bWFuaWZlc3Q=",
"name": "TestApp.msi",
"size": 0,
"sizeEncrypted": 0,
"uploadState": "azureStorageUriRequestPending"
}
What could be the problem?

Answer 1

Fisrt,as #Marc Lafleur said, you need to upload the file to Azure sotrage first and then provide the required Property value of them.
Second,In your request body, you didn't fill with full required properties.
Follow this example to create one mobile app content file :
POST https://graph.microsoft.com/beta/deviceAppManagement/mobileApps/{mobileAppId}/contentVersions/{mobileAppContentId}/files
Content-type: application/json
Content-length: 342
{
"#odata.type": "#microsoft.graph.mobileAppContentFile",
"azureStorageUri": "Azure Storage Uri value",
"isCommitted": true,
"name": "Name value",
"size": 4,
"sizeEncrypted": 13,
"azureStorageUriExpirationDateTime": "2017-01-01T00:00:08.4940464-08:00",
"manifest": "bWFuaWZlc3Q=",
"uploadState": "transientError"
}
