show error stack

#

seems like not a error with canvas tbh

#

error stack, not code

#

could you log attachment?

#

thats the issue

#

canvas.encode, not .toBuffer

#

which canvas package u using?

#

hmm...

#

Shouldn't you use a mime type for toBuffer?

#

you can also not pass in any parameters, it should still create a PNG buffer

#

e.g.
canvas.toBuffer() <- still should make it a PNG
or
canvas.toBuffer('image/png');

#

This is the signature for the function.

canvas.toBuffer((err: Error|null, result: Buffer) => void, mimeType?: string, config?: any) => void
canvas.toBuffer(mimeType?: string, config?: any) => Buffer
#

Should be pretty simple from what you have now.

just get the canvas.height and width, select 0 as 1 param in start coords, and place the canvas width and height in end coords
