`gds.alpha.sllpa.stream` : graph does not support `write` execution mode.

Describe the bug

I'm trying to run gds.alpha.sllpa.stream and got error: The provided graph does not support write execution mode. Why does the stream mode requires the graph to support write mode? How can I allow the graph to support write mode? I'm creating my graph using gds.alpha.graph.construct. Thanks!
