From the error message:

Error: Invalid width (1 to 16383) image/jpeg at Sharp.resize

... it looks like the value you're passing for "width" is the string "image/jpeg". Of course, it should be a number, not a string :)

Check the .NET code that's calling InvokeAsync and the parameters it's passing, and make sure it matches up with your Node code that's receiving these parameters. My guess is that you're trying to send a different number of parameters than you're receiving, or you're trying to receive them in a different order than they were sent.
