Issue with using Web API code to pull in Dynamics saved query

I am currently in the process of trying to query and existing Dynamics query using the Web API query method and have received the below error:

DataSource.Error: Microsoft.Mashup.Engine1.Library.Resources.HttpResource: Request failed:
OData Version: 3 and 4, Error: The remote server returned an error: (400) Bad Request. (Could not find a property named 'Test' on type 'Microsoft.Dynamics.CRM.savedquery'.)
OData Version: 4, Error: The remote server returned an error: (400) Bad Request. (Could not find a property named 'Test' on type 'Microsoft.Dynamics.CRM.savedquery'.)
Details:
DataSourceKind=OData
DataSourcePath=https://myorgurl.com/api/data/v8.0/savedqueries

I have confirmed that my query is saved accurately. Is there any other issues that could be causing this? I have queried information via web api using alternatives methods successfully so I know it is just related to this single query.

Just fyi - the original code I am using was provided in the below post:

Thank you for any help you can provide,
