No Type on collections page or Tiles heading in the collection when only provider is OA-Tiles
Description
When a collection has only a provider for MVT to serve OGC API - Tiles, the HTML pages at the /collections/ level have Type = blank for that collection. The HTML page for the collection itself, doesn't have a subheading "Tiles" with link to the Tiles url eg http://pygeoapi-2018-main.kube-idev.bgslcdevops.test/collections/BGSGeology625kBedrock/tiles as the user sees when there is also OGCAPI - Features available.
Steps to Reproduce Steps to reproduce the behavior:
Expected behavior HTML pages for tiles only collections should match feature + tiles collections
On the /collections/ pages Type should be "Tiles"
When Features and Tiles are available Type = "Features, Tiles"
Screenshots/Tracebacks
Type is blank
No Tiles subheading although link to Tiles as HTML and Tiles as JSON is available
Expected layout with Tiles subheading, as generated when OA-Features also present
Environment
- OS: Docker image
- Python version: Docker Image
- pygeoapi version: 0.11dev0
Additional context Add any other context about the problem here.
See current config https://github.com/BritishGeologicalSurvey/bgs-pygeoapi
I have a similar issue, but the "tiles" keyword does not appear also when along with OGC API Features - only "feature" is displayed at collection level.
Then the tiles are exposed in the links of the collection
But an error is displayed, when trying to access them:
