WebApi: OData returns error on /Products?$top=120&$expand=ProductCategories

[TripleNico]

Currently i'm preparing the update from 3.2.2 to v.4.1.1. meaning i have to update the OData client from v3 to v4. During the adjustment i bumped into a problem that GET /odata/v1/Products?$top=120&$expand=ProductCategories returns the error

    "code":"","message":"An error has occurred.","innererror":{
      "message":"The 'ObjectContent`1' type failed to serialize the response body for content type 'application/json; charset=utf-8; odata.metadata=minimal'.","type":"System.InvalidOperationException","stacktrace":"","internalexception":{
        "message":"The specified type member 'MergedDataValues' is not supported in LINQ to Entities. Only initializers, entity members, and entity navigation properties are supported.","

Checking the OData Metadata than this should work? When i try it with a different object like GET /odata/v1/Customers?$top=120&$expand=CustomerRoleMappings then everything works as expected.

Am i overlooking something of is this not working in v4?

I don't know. You'll probably get it faster if you compile it yourself. It's Open Source.

Thanks for the link! Just tried to build it but it seams that the WebApi isn't build by the ClickToBuild.cmd script. The rest of the plugins build just fine.

Update; It's because WebApi isn't part of the solution. Adding the WebApi to the plugin folder in the solution fixes the problem.
