Unable to filter on headers

The following used to work for me but after upgrading to a more recent version it no longer does:

return headers["EVENT_TYPE"] == "ContractLineEndRequestedEvent";

Filtering on fields still works.

I'm not sure that it does @weeco

In the following image you can see that the header text is not escaped for me.

Thanks in advance :)
