You're encountering an issue with GroupBy operation in LINQ query. This error message could suggests that the GroupBy pattern cannot be translated and is asking you to call AsEnumerable before GroupBy to evaluate it client-side.

When using the LINQ, GroupBy is typically used to group data on the server side. But, sometimes the server-side translation fails, and you need to execute the GroupBy operation client-side. This is where AsEnumerable comes in.

AsEnumerable makes it so you can execute the GroupBy operation on the client side, instead of on the server. By calling AsEnumerable before GroupBy, you're essentially telling LINQ to bring the entire data set back to the client and perform the GroupBy operation locally, rather than trying to translate it to the server.

So, to resolve this issue, you should add a call to AsEnumerable before the GroupBy operation, like this:

data.AsEnumerable().GroupBy(x => x.SomeProperty)
