Build-Function script is throwing an error

[Schuckknight]

We are using the self hosted version of the portal and running into an error during the Build-Function command. This error also occurs in the latest azure dev portal code, not just our version.

Reproduction Steps: 1) Run the command "npm run build-function" 2) The output will show that an error is occurring due to a missing canvas npm package.

The outputted error is a mistake in my opinion. Canvas is an optional dependency of the jsdom npm package. There are other optional npm package dependencies (for example, bufferutil and utf-8-validate) in the latest azure dev portal code, but these just throw warnings. The error that is thrown due to the optional canvas package is causing our azure pipeline to fail because the build-function command returns a non zero value because of this error.

Relevant output from running command "npm run build-function"
