Hi @andym331,

Many thanks for the PR! However, although it work in the MI, it doesn't using rgcam. See below:

Line 240 main.R

bq
$regions
character(0)
$query
[1] "<emissionsQueryBuilder title="CO2 emissions by tech (nested subsector) (excluding resource production)">\n <axis1 name="technology">technology\n <axis2 name="Year">emissions\n <xPath buildList="true" dataName="emissions" group="false" sumAll="false">[@type = 'sector' ]/[@type='subsector']//*[@type='technology']//\n CO2/emissions/node()\n \n"
$title
[1] "CO2 emissions by tech (nested subsector) (excluding resource production)"

Line 253 main.R

table <- suppressMessages({
rgcam::runQuery(conn, bq$query, sc, bq$regions, warn.empty = FALSE)
})

Still trying to understand why it works in the MI and not through rgcam
