Query option 'Format' is not allowed. To allow it, set the 'AllowedQueryOptions' property on EnableQueryAttribute or QueryValidationSettings

Question

I'm getting an exception on my Web API controller endpoint and I would appreciate some help solving it.

Here is the story:

In my Web API project, a controller exposes the following endpoints:

My Kendo UI Datagrid makes the following request:

http://localhost:63865/api/employees/GetAll?$callback=jQuery21109420544053427875_1410883352953&%24inlinecount=allpages&%24format=json&%24top=5

I'm getting this exception when validating the ODataQueryOptions sent in the request:

Query option 'Format' is not allowed. To allow it, set the 'AllowedQueryOptions' property on EnableQueryAttribute or QueryValidationSettings.

But I've enabled all query options:

[EnableQuery(AllowedQueryOptions=AllowedQueryOptions.All)]

What am I doing wrong ?

Answer 1

Finally manage to get to the bottom of this!

After creating the ODataValidationSettings object I needed to change the AllowedQueryOptions to AllowedQueryOptions.All. Be default all options are there except the Format and SkipToken.

Anyway, hope this may help anyone else facing the same issue.
