I am repeatedly getting this error when trying to load mapbox with 3 markers from database data. I tried with png, jpg, svg files but no luck. Anyone has any idea why this might be happening?
I even tried sample icon files from internet but the error does not go away at all.
Just so that you know - i finally found the issue - API key was expired and Mapbox plugin was throwing an error which was quiet misleading - nothing wrong with the icon image or url.
