Uncaught Error: No value provided for variable {s}

[pedrovgp]

I am trying to follow the instructions here https://storymap.knightlab.com/advanced/ to render local pictures in a storymap.

The html and pictures are locally stored and I am using "python -m http.server" to serve the html.

But the leaflet map does not load. I am getting the exception below.

Browser traceback:

I encountered the same exception. For my case, it was happening when all or none of the markers were set as "type": "overview". I set only the first one to be of type overview and the error is gone.
