Request error on table when using "ALL" with a variable"

Using the Azure Log Analytics plugin, I’m using a TABLE visualization to return a list of Computers (over 8000). I set up a variable so that I can search for any computer in the visualization. This works perfectly if I do not turn on the “Include All option” in the variable settings. Once I turn that on (I want the default value of ALL, so I can page through all 8k of the computers) , I immediately get the “Request error” message (with no detail):

If I trim my results down (limit to 50 for example), the ALL option doesn’t cause this problem. What am I doing wrong, and how can I fix this?

Thanks!
