Vega Chloropleth Map Visualisation - maps

Question

For some reason vega is reading my data as 0 when the numbers range from 1-234.
I am attempting to show a visualisation of a chloropleth map of crypto-ownership by country.
The countries have been ranked 1-234 and that is meant to show on the tooltip however, this is being shown as 0 on the tooltip. How do I fix this.
Here is my code:
{
"$schema": "https://vega.github.io/schema/vega-lite/v5.json",
"title":{
"text": "Crypto Ownership Worldwide",
"subtitle": "Source: FILL",
"anchor": "start"
},
"width":500,
"height":400,
"data": {
"url": "https://raw.githubusercontent.com/tomiwav/tomiwav.github.io/main/custom.geo%20(3).json",
"format":{"property": "features"}
},
"projection":{"type": "mercator"},
"transform": [
{
"lookup":"properties.name",
"from":{
"key": "Country",
"fields": ["Rank"],
"data":{
"url": "https://raw.githubusercontent.com/tomiwav/tomiwav.github.io/main/datarank.csv",
"format":{"type":"csv"}
}
}
}
],
"mark":{
"type": "geoshape",
"fill":"lightgray",
"stroke":"black",
"strokeWidth":0.5
},
"encoding": {
"color": {
"field": "Rank",
"type": "quantitative",
"scale": {
"domain":[234,1],
"scheme": "oranges"
}
},
"tooltip":[
{"field":"properties.name", "title":"Country"},
{"field":"Rank","type":"quantitative","title":"Number of Crypto Owners","format":".2f"}
]
},
"config": {"mark": {"invalid": null}
}
}

Your lookup was failing. You need a lower case "c" on country.

}
]
