MS Graph API: contains filters does not work on property serialNumber of deviceManagement/managedDevices

Question

The following query fails on 1.0 and beta endpoints, it returns 200 OK with empty data if serial number is partial.

GET https://graph.microsoft.com/beta/deviceManagement/managedDevices?$filter=contains(serialNumber,'ABC')

If full serial number is provided, it returns a single device successfully (it behaves like eq operator).

Tried with other properties like deviceName and it works flawlessly: https://graph.microsoft.com/beta/deviceManagement/managedDevices?$filter=contains(deviceName,'a')

Answer 1

@Gabriel Guillem Barceló Soteras, Thanks for posting in Q&A. Based on my testing, I find it can work in my environment. I can get the device information with the serial number. Here is the screenshot for your reference

You can change to other serial number to see if it can query. Or open a new Graph Explorer to see if the result will be different.
