Hi Andrew Weller,
You will encounter such an error if:
- Your data includes geographic data outside the coordinate bounds of 90°,-90°, 180°,-180°
- You are using projected data and you are missing the spatial reference information; for example if you have a shapefile (which is made up of many files - .shp, .shx, .dbf) and you are missing the .prj file, Tableau will make a guess that you are using geographic coordinates and show this error
- Can you share this data (even a subset zipped up)?
- Can you simply inspect the data in QGIS and report back the coordinate reference system? (Right-click on a layer in QGIS and look at the CRS):
Let me know.

Note: When you export a shapefile from mapshaper.org, you will get the required files and .prj file. I've just verified this myself.
Although it says EPSG:4326, the coordinate values within the dataset are clearly projected and look more like meters or feet, not decimal degrees. So the .prj is not correct.
Did you download this from a public source?
Yes, I downloaded this from WAOFM - GIS - Legislative District Boundary | Data.WA | State of Washington (Export -> Download As -> Shapefile)
When I download it as a GeoJSON instead of Shapefile, it loads perfectly.
Let me know if you need anything else.
