8.0.3 fails with error Value cannot be null. (Parameter 'structuredType') . May be because Autoexpand and EnableQuery Conflicts

Short summary (3-5 sentences) describing the issue.

If we use ENableQuery Attribute in our controller Action method defined as part of .netcore. Error comes that Value cannot be null. (Parameter 'structuredType') . The reason seems Enable Query and AutoExpand are not working if both are present. in 8.0.3

Assemblies affected

*Which assemblies and versions are known to be affected microsoft.aspnetcore.odata\8.0.3\lib\netcoreapp3.1\Microsoft.AspNetCore.OData.dll

Reproduce steps

The simplest set of steps to reproduce the issue. If possible, reference a commit that demonstrates the issue.

We have an GttpGet action in the controller defined EnableQuery and it returns Ilist

Now if we remove the EnableQuery. The get operation works. Also if we remove [AutoExpand] expand attribute then also it works.

But we want to keep both attributes. The error which pops out is "Value cannot be null. (Parameter 'structuredType')"

We have below Contracts:
