Hello ; the code please?

LorenzBuehmann commented 7 years ago

@walidrelupo the code for what?

walidrelupo commented 7 years ago

@LorenzBuehmann , the query!

KonradHoeffner commented 7 years ago

@walidrelupo thanks for participating! However this issue got opened a long time ago and the code is not actively maintained anymore. If I understand you correctly, you want to see the SPARQL query that caused the error. Unfortunately I cannot replicate this at this time.

@KonradHoeffner , it's my pleasure to help , good luck.
