Unable to build

This is a Bug Report / Question

Description

Trying to build the extension in order to test/submit a PR.

• What went wrong?

Cannot build master branch

• What did you expect should have happened?

Source should have built

• What was the config you used?

node@8 and node@11, usual npm install, building inside VSC

• What stacktrace or error message from your provider did you see?

Build exits with this error:

src/lib/serverlessOutline.ts(124,31): error TS2459:
   Type 'string' has no property 'http' and no string index signature.

Is there a configuration etc. that I'm missing?
