) ## Why make this change? - Fix issue #3662 This issue is caused by a regression in PR #3080 The regression is that we start using the raw encoded URL and we assume that the `$` character is not encoded when using the `ExtractRawQueryParameter` function, this is half true, since depending on where the URL comes from it will encode it or it will treat it as a special character and leave it as it is. This means the function looks for the `$filter` or `$orderby` when the URL has the possibility to change them to `%24filter` or `%24orderby` which causes the failure. ## What is this change? This change fixes a bug that caused using `$filter` or `$orderby` in REST. This is done by encoding the `parameterName` so that it has the same format as the raw URL, it will only change it if it is unable to find the original `$` character in the raw query. ## How was this tested? - [ ] Integration Tests - [x] Unit Tests Added end to end test to ensure that REST requests that use `$filter` and `$orderby` succeed for both cases where a user uses the special character `$` or its URL encoded format `%24`. ## Sample Request(s) http://localhost:5000/api/Book?$orderby=id desc http://localhost:5000/api/Book?$filter=publisher_id 1234

Pull request overview
Cherry-picks a fix to REST OData query parsing so $filter / $orderby work reliably whether the $ is present literally or URL-encoded as %24, and adds an end-to-end regression test to validate both forms.
Changes:
- Update
RequestParser.ExtractRawQueryParameterto fall back to an encoded parameter name when the raw query string doesn’t contain the unencoded key. - Add an MSSQL end-to-end REST test covering both
$filter/$orderbyand%24filter/%24orderbyrequests.
