adaro/lib/patch/index.js:121:21: TypeError: Cannot read property 'name' of undefined

After I updated dustjs modules in my Kraken application, I get following error while rendering the dust page:

TypeError: Cannot read property 'name' of undefined

These are my dustjs modules:

"dusthelpers-supplement": "^1.0.0",
    "dustjs-helpers": "^1.7.3",
    "dustjs-linkedin": "^2.7.0",
    "ppdustjs-filters-secure": "0.0.2",
    "grunt-dustjs": "^1.2.1"

My view engine configuration in config.json:

"view engines": {
        "js": {
            "module": "engine-munger",
            "renderer": {
                "method": "js",
                "arguments": [
                    { "cache": true, "helpers": [ "ppdustjs-filters-secure", "dustjs-helpers" ] },
                    {
                        "views": "config:express.views",
                        "view engine": "config:express.view engine",
                        "i18n": "config:i18n"
                    }
                ]
            }
        }
    },

Any idea why adaro is throwing this error? Is there a specific dustjs version which needs to be used to resolve this error?

[aredridel]

Which version of adaro?

dust 2.7 is not compatible with engine-munger 0.2.x

[prabhash1785]

I have adaro 0.1.7 and engine-munger 0.2.4

Let me try to update adaro to 2.0.0-4 and egnine-munger to 1.1.1 and see if this resolves the issue.

[prabhash1785]

Nope, updating adaro and engine-munger to latest version did not help.

Finally I downgraded my dust version to 2.6.2 and everything works now. Here are the versions I am using:

"adaro": "~0.1.7",
"dusthelpers-supplement": "~0.0.4",
"dustjs-helpers": "~1.6.3",
"dustjs-linkedin": "~2.6.2",
"engine-munger": "^0.2.4"

[prabhash1785]

By the way, lets say if I have to use Dust version 2.7 then what version of engine-munger and adaro are supposed to be used or are they not compatible at all?

[aredridel]

engine-munger 1.0.0, adaro 1.0.0, dust 2.7 go together -- it was the focus of my major rewrite, since dust 2.7 (Beware! no semver in dust!) removed the load method that they all tweaked.

Cool! Good to know! Thanks for your help, @aredridel!

I will close this issue.
