Generating interfaces throws an error

[connorshea]

I ran the following commands:

• git clone https://github.com/mdittmer/mdn-confluence
• cd mdn-confluence
• npm install && npm run build (this failed due to a lack of the mdn-bcd package from the source repo)
• npm install mdn-browser-compat-data@git://github.com/mdn/browser-compat-data.git
• npm install && npm run build
• npm run generate -- --interfaces=HTMLDocument

The last command errored for me:

connorshea$ npm run generate -- --interfaces=HTMLDocument

> mdn-confluence@0.0.7 generate /Users/connorshea/Programming/mdn-confluence
> node ./main/generate.es6.js "--interfaces=HTMLDocument"

I assume this line in particular is important:

Version info:

• node.js v8.11.2
• npm 6.4.0
• macOS High Sierra 10.13.6 (latest stable release)

This seems to happen in NodeJS v9.11.2 (not a typo, for some reason I happen to have both 8.11.2 and 9.11.2) as well. It also doesn't seem to matter what interfaces I pass to it.

Thanks for filing! It looks like the most recent data push for Confluence didn't properly update a data blob that's used by mdn-confluence. (Didn't get caught, in part, because confluence itself doesn't use that particular data model anymore.)

Anyway, I pushed new GridRow data so this should be fixed. @connorshea please confirm. Fix should be locked in to confluence data publishing workflow by https://github.com/GoogleChromeLabs/confluence/pull/319.

👍 It looks like this fixes the problem for me, thanks!
