TELERIK Grid Blazor- Type arguments for parameter cannot be inferred from usage

Type arguments for method TypeInterface.CreateTelerikTreeList_1(RenderTreeBuilder, int, int, IEnumerable, int, RenderFragment) cannot be inferred from use.

This error appears when my api returns this:

{ "middlewareId": "string", "description": "string", "protocol": "string", "server": "string", "port": "string", "path": "string", "user": "string", "active": true } 

The error appears the line of the <TelerikTreeList Data="InfoMiddleware">

I do something similar with the Flow to generate a Telerik Grid but for this case the api is sending something like this and in this case it is creating the table without error.

[ { "flowId": "string", "middlewareId": "string", "Active": true } ] 

<TelerikTreeList Data="InfoMiddleware"> <TreeListColumns> <TreeListCommandColumn> <TreeListCommandButton Icon="edit">Edit</TreeListCommandButton> </TreeListCommandColumn> <TreeListColumn Field=@nameof(MiddlewareModel.MiddlewareId) Title="Middleware"/> <TreeListColumn Field=@nameof(MiddlewareModel.Description) Title="Middleware"/> <TreeListColumn Field=@nameof(MiddlewareModel.Protocol) Title="Middleware" /> <TreeListColumn Field=@nameof(MiddlewareModel.Server) Title="Middleware" /> <TreeListColumn Field=@nameof(MiddlewareModel.Path) Title="Middleware"/> <TreeListColumn Field=@nameof(MiddlewareModel.UserName) Title="Middleware"/> <TreeListColumn Field=@nameof(MiddlewareModel.Active) Title="Middleware" /> </TreeListColumns> </TelerikTreeList>
