EMPTY POLYGON

[jelade]

I have installed all the dependencies but I am trying to run the Iso-Area as Interpolation (from Layer)

this is the return I am getting when running it

[QNEAT3Network][calcEntryCostEllipsoidal] Ellipsoidal entry cost to vertex 81401 = nan
[QNEAT3Network][calcEntryCostEllipsoidal] Ellipsoidal entry cost to vertex 81402 = nan
[QNEAT3Network][calcEntryCostEllipsoidal] Ellipsoidal entry cost to vertex 81403 = nan
[QNEAT3Network][calcEntryCostEllipsoidal] Ellipsoidal entry cost to vertex 81404 = nan
[QNEAT3Network][calcEntryCostEllipsoidal] Ellipsoidal entry cost to vertex 68299 = nan
[QNEAT3Network][calcEntryCostEllipsoidal] Ellipsoidal entry cost to vertex 81405 = nan
[QNEAT3Network][calcEntryCostEllipsoidal] Ellipsoidal entry cost to vertex 81406 = nan
[QNEAT3Network][calcEntryCostEllipsoidal] Ellipsoidal entry cost to vertex 80175 = nan

The polygon scale bar add very large positive and negative range without any polygon
