Modding Help nightly capturepods

I'm trying to get my creaturecages mod working with nightly (since the current stable has only critters ). Unfortunatly, I'm having trouble figuring out how the attach a script to the monster that will be displayed.

Previously:

Code:

 creature["arguments"]["scripts"] = {"/objects/generic/creaturecage/cagedcreatureai.lua"}
world.spawnMonster(creature["type"], {entity.position()[1], entity.position()[2] + 2}, creature["arguments"])

Now:

Code:

parameters["scripts"] = "/objects/generic/creaturecage/cagedcreatureai.lua"
storage.displayMonster = world.spawnMonster(monsterStored.config.type, entity.position(), parameters)

However, the new parameters for spawning a monster don't seem to have a scripts parameter and trying to add one results in "Could not spawn Monster of type 'gleap', exception caught: (JsonException) Improper conversion to JsonArray from string"

Any ideas about attaching a script to these guys?
