WikiMiniAtlas: Using parameters leads to "Coordinates: Extra unexpected parameters"

Question

I want to add a "dim:" (Dimension) parameter to "coord" at https://en.wikipedia.org/wiki/Wakasu so that the mini-map (click the globe in the upper-right) shows just the island (2 kilometers diameter), not the whole continent.

So I changed:

{{coord|35|37|N|139|50|E|display=title|region:JP_type:city_source:GNS-enwiki}}

... to:

{{coord|35|37|N|139|50|E|display=title|dim:2000|region:JP_type:city_source:GNS-enwiki}}

PROBLEM: I get an error Coordinates: Extra unexpected parameters.

What am I doing wrong? The documentation seems to imply it should work.

Answer 1

WikiMiniAtlas developer here. Replace the | between 2000 and region with a _

{{coord|35|37|N|139|50|E|display=title|dim:2000_region:JP_type:city_source:GNS-enwiki}}

That should work.
