Re: [igraph] Error: "At iterators.c:721 : Cannot create iterator, invalid vertex id, Invalid vertex id" while computing shortest path

[Gábor Csárdi]

Hi,

exactly what the error message says, you supplied an invalid vertex id
to shortest.paths(). Most likely you forgot that vertex ids are
indexed from zero. But it is hard to say for sure, since we don't know
what you did.

Best,
Gabor
