Stream yields empty buffer

[Portur]

Hi,

App is running 100%. (Node v12.16.1)
Character info is retrieved successfully.
Assets and images are stored to tmp and is viewable.

When the image is generated an error is returned 'Stream yields empty buffer'

Issue solved setting
const gm = require("gm").subClass({ imageMagick: true})
to
const gm = require("gm")

And had to install GraphicsMagick
