External service for approve responder isn't working

[mpadge]

We currently have our approve responder configured like this:

buffy/config/settings-production.yml

Lines 68 to 84 in 044d630

	ropensci_approve:
	only: editors
	external_service:
	name: badge
	url: http://138.68.123.59:8000/badge
	method: get
	data_from_issue:
	- repo
	- repourl
	- issue_id
	template_file: approved.md
	data_from_issue:
	- reviewers-list
	remove_labels:
	- 5/awaiting-reviewer(s)-response
	add_labels:
	- 6/approved

The external service calls this plumber function which in turn calls roreviewapi::readme_badge(). That function should then confirm in the issue whether the repo has an rOpenSci badge in its README. That external call is, however, not made.

The external service in the welcome responder works:

buffy/config/settings-production.yml

Lines 27 to 40 in 044d630

	welcome:
	if:
	value_matches:
	submission-type: "Standard|Estándar|Stats"
	message: "Thanks for submitting to rOpenSci, our editors and @ropensci-review-bot will reply soon. Type `@ropensci-review-bot help` for help."
	external_service:
	name: editorcheck
	url: http://138.68.123.59:8000/editorcheck
	method: get
	data_from_issue:
