Roll20 Audio Manager - Can't Import Tracks

Hello, I'm trying to setup the Roll20 Audio Manager script in a new game. I've added a couple of songs to the Jukebox, however when I try to invoke the command !roll20AM --config,import I get the following error: SyntaxError: Unexpected end of JSON input at JSON.parse (<anonymous>) at importJukebox (apiscript.js:1532:33) at configHandler (apiscript.js:824:13) at Timeout._onTimeout (apiscript.js:584:17) at listOnTimeout (internal/timers.js:549:17) at processTimers (internal/timers.js:492:7) I've tried restarting the sandbox a number of times and changing the version of the AM that is loaded. The only other API I have loaded is  5th Edition OGL by Roll20 Companion . Any help would be appreciated.
