I am trying to connect pairs of points by lines using the Points2One tool in QGIS. I have created the data and exported it as shapefile. The data looks similar to the data in this question: Workflow for creating line features between two coordinate pairs in QGIS
The problem is after grouping the data by id and sorting by order I get an error which says
"Can't make a polyline out of one points." I am not sure what I am doing wrong here as I am new to QGIS.
Here's the attribute table: id, order, longitude, latitude stream1, 1, 80.187006, 12.989196 stream1, 2, 78.509647, 17.441657 stream2, 1, 78.454394, 17.242307 stream2, 2, 80.157087, 13.112136
