"targetModule" should be a string - marko-hydrate error

[BryceEWatson]

One of my pages is failing with the below stack:

Exception: Error: Failed to walk dependency [marko-hydrate:
.........
Cause: AssertionError [ERR_ASSERTION]: "targetModule" should be a string
    at module.exports (/Users/brywatson/e4csite/node_modules/lasso/node_modules/raptor-util/createError.js:7:50)
    at walkDependency (/Users/brywatson/e4csite/node_modules/lasso/src/dependency-walker.js:123:23)
    at <anonymous>
    at process._tickDomainCallback (internal/process/next_tick.js:228:7)

I added some debug logic at lasso/src/resolve/index.js:29 and found that the below less object is coming in the targetModule and causing the crash:

{ type: 'less',
  code: '.app-terms {\n        background-color: #FFF;\n    }\n    .terms__container {\n        padding: 0px 35px 35px 35px;\n    }',
  virtualPath: './index.marko.less',
  path: './index.marko' }

If I remove the style from this template it will use the next less style it finds to cause the crash. This does not happen on other pages that are loading in what appears to be identical ways.

I'm using marko@4.7.5 lasso@3.1.2 and lasso-marko@2.4.0

Note: Downgrading to lasso-marko@2.3.1 fixes the issue, so maybe there is some other issue with latest lasso-marko?
