Reading the exception, it seems that the problem is that your results are simply too large. I did not anticipate this, so the current way it does this is a simple text replace, so you need to have the entire results object as text in memory. If you have a lot of log lines to include, this could potentially be a large chunk of contiguous memory.
Not sure why it is attempting to compress this message though. But it could be because something else fails that it gets a null error.
