It's interesting that in the spec, it seems like a parenthesis is required.

Does it change the error if you do something like this?
$apply=groupby((Technology,Status))

You right, the sample I provided is missing the inner parenthesis - I fixed it in the description above. (The exception is thrown when providing the right syntax - if the inner parenthesis are missing, the exception is specific for the missing parenthesis)

This seems to be a regression. @ElizabethOkerio will investigate.
