Error to get the relation label

[EricFerreiraS]

I'm using the python kgtk library to work with the cskg.tsv file. When I execute the following query: kgtk(""" query -i cskg.tsv --match '(n1)-[r]->(n2)' --where 'n1.label="bicycle"' --return 'n1.label, n2.label, r.relation' --limit 3 """) I got the values `

node1;label	node2;label	relation
bicycle	bicycle shop	/r/AtLocation
bicycle	garage	/r/AtLocation
bicycle	lab	/r/AtLocation
`

but when I change to
kgtk(""" query -i cskg.tsv --match '(n1)-[r]->(n2)' --where 'n1.label="bicycle"' --return 'n1.label, n2.label, r.label' --limit 3 """)
I got the following error: `Exception in thread background thread for pid 81394:

STDOUT:

STDERR:

no such column: graph_1_c1.label`

Is there any way to get the relation's label? When I run the query without the return parameter, I see a column with the label.
