Graph API - use variable in filter query

Question

I am calling the Microsoft Graph API's to import user details into an application (which uses REST based connector) from Azure AD.

The application provides a variable (xyz) to be used in order to do incremental user imports.

I need to pass the application variable as ${xyz}. The Graph query seems to be confused about the $ symbol and is throwing an illegal character exception for the $ sign.

Below is the GET query used:

"https://graph.microsoft.com/v1.0/users?$select=id,displayName,userPrincipalName,mail,accountEnabled,onPremisesLastSyncDateTime&$count=true&$filter=onPremisesLastSyncDateTime%20ge%20${xyz}"

Error: [22;39mjava.lang.IllegalArgumentException: Illegal character in query at index 182:

Have tried to use $$, single quotes,backslash,` etc. to fix the issue, but none worked. Any help would be much appreciated.

Answer 1

As @Dmitry Streblechenko suggested, the error indicates that the variable does not have any real data.

If the real data is passed to the variable, the Graph API call runs successfully
