TypeError: Can't use 'in' on a non-object - cheerio npm module in trireme

[firefoxNX]

Sorry for the cross-post from https://community.apigee.com/questions/14176/typeerror-cant-use-in-on-a-non-object-with-trireme.html

I have a nodejs app as target endpoint in one of my api proxies. I am using
"email-templates": "^2.0.1" NPM module. It runs fine when I run with node.js runtime. But when running on trireme locally (version Trireme 0.8.8) or in edge server (on-prem ver 4.15.04.00) I get below exception

TypeError: Can't use 'in' on a non-object.

cheerio static.js line # 81 is

if (Object.prototype.toString.call(dom) === '[object Object]' && !options && !('length' in dom) && !('type' in dom))

Any idea on why this is not working? When I remove && !('length' in dom) && !('type' in dom) it works fine.

Do you have a reproduction recipe? Without knowing what dom is, I have no idea how to reproduce it. Of course, using 'prop' in obj where obj is null, undefined or a non-object produces the expected output.

Ran into the same issue. Looks like Object.prototype.toString.call(undefined) returns "[object Undefined]" in node but "[object Object]" in trireme.
