Why does https://graph.microsoft.com/v1.0/sites need a blank search parameter to return a list of sites?

According to docs, you should be able to make a request to https://graph.microsoft.com/v1.0/sites and get a list of your Sharepoint sites back. Both in the Graph API explorer and with my own HTTP requests, this seems to always return an empty list.

However, if I add a blank search parameter (i.e. make a request to https://graph.microsoft.com/v1.0/sites?search=), I do get all of my sites back.

Is that a bug or a feature? Do you need to include an empty search parameter for other endpoints in the Graph API?

Thanks! Taylor

    Well, according to the documentation, only application permissions are supported for that query, so it shouldn't even work in the Graph explorer. Not sure if bug, improperly documented feature or anything else, but I will ping few people as it's interesting to know the answer here :)

    Hi @Taylor Reece

    Per my research, https://graph.microsoft.com/v1.0/sites only support Application permission. So we are unable to call GET /sites in the graph explorer tool.

    And in the search for sites document, this is a different endpoint with GET /sites. The endpoint support Delegated (work or school account). So we will get result in the graph explorer tool while GET /sites returns empty.
