Why is $filter=eq() an invalid filter clause on /users?

Question

Does anyone know why this fails?

Request: GET https://graph.microsoft.com/v1.0/users?$filter=eq(employeeId, '1.0.3384')

Response:

{
    "error": {
        "code": "BadRequest",
        "message": "Invalid filter clause",

If I use $filter=startsWith() instead, this works fine, but I have use cases where eq() is desired.

Answer 1

Your eq filter parameters are used incorrectly. You only need to make a small modification and the problem should be solved.

https://graph.microsoft.com/v1.0/users?$filter=employeeId eq '1.0.3384'
