filename of undefined error when used with mocha

[austinmao]

I am getting TypeError: Cannot read property 'filename' of undefined from node-source-map-support when running mocha. By manually going into that package and doing a console.trace(), I get this stack trace below:

TypeError: Cannot read property 'filename' of undefined
npm ERR! Test failed.  See above for more details.

The weird thing is that this doesn't happen in Codeship. The problem goes away when I downgrade to package v6.0.0 (without node-source-map-support).

I'm not so familiar with these two packages, so would you know how to fix this so I can actually get source map support back?

[austinmao]

Any update on this?

[dangreen]

@austinmao can you provide example of your test?

@austinmao try to install package from git (npm install https://github.com/sane/sails-hook-babel.git) and test it

[sd031]

I am getting this issue too ,
issue:
/node_modules/source-map-support/source-map-support.js:415
var hasStack = (arguments[1] && arguments[1].stack);
^

TypeError: Cannot read property 'filename' of undefined

I am using:
sails 0.12.3
node.js v6.9.1

[dangreen]

@sd031 Have you tried it?

[rkbrewer]

Thanks @dangreen. I was getting the same issue @sd031 was getting, but installing sails-hook-babel from git fixed it.

My buggy setup that got fixed was:
sails 12.4
node: 6.5
sails-hook-babel: 6.0.1

[dangreen]

npm package was updated
