DocFX Version Used: 2.40.11.0

Template used: custom template

Steps to Reproduce:

I undoubtedly have a mistake in my template, either in the JavaScript or in the Mustache. I can't tell. The problem is very much that I can't tell what the problem is, because DocFX doesn't show me any error message. This is what I see a 100 times:

[19-02-20 03:05:17.969]Error:[BuildCore.Build Document.LinkPhaseHandlerWithIncremental.Apply Templates](api/Amazon.CDK.AWS.KMS.EncryptionKeyAliasProps.yml)Error transforming model "/var/folders/y2/gfhldsms0bdbck1zjl2647gnr9xt2d/T/docfx/rawmodel/api/Amazon.CDK.AWS.KMS.EncryptionKeyAliasProps.raw.json" generated from "api/Amazon.CDK.AWS.KMS.EncryptionKeyAliasProps.yml" using "ManagedReference.html.primary.js". Error running Transform function inside template preprocessor: 

I have no idea how to use the tool to give me more details on the error it encountered.

Expected Behavior: Error message and stack trace tells the cause of the error (JavaScript error message, or otherwise). I noticed that if I do throw new Error(...) in the transformer I do see the error message, so I must have hit a messageless error, for which the lack of stack trace is causing me a problem right now.

Actual Behavior: Error message tells me there is a problems somewhere in the (potentially large) file.
