Spawning items with the vanilla command throws error and failts to spawn item

[ren-kun]

Say i use the folllowing command (be it syntax correct or not)

/spawnitem mininglantern 1 '{"beamAmbience":999999999, "beamLevel":999999999,}}'

The following error occurs

Traceback (most recent call last):

This happens every time you try to use that command?

I'm unable to replicate the issue on the latest version (7d939f0) or on my production server.

I will update and try again soon
