Ross,

Were you able to try the 2.1.0 beta binaries?  

This issue should be fixed on those.

Thanks,

Regina

Subject: [pgrouting-users] TRSP error - Invalid result geometry
node_id:-1edge_id:0

Hello list

I am getting an error using the pgr_trsp function with vertices.

[Invalid result geometry node_id:-1 edge_id:0] using the pgRouting Layer
plugin in QGIS

The query is:

SELECT *

FROM pgr_trsp('SELECT gid as id, source::integer, target::integer,
cost_len::float AS cost

FROM itn_network', 

 30,

60, 

 false, 

 false

);

Result

0;-1;0;0 using PgAdmin

If I use the function with edges then it works as expected

SELECT *

FROM pgr_trsp('SELECT gid as id, source::integer, target::integer,
cost_len::float AS cost

FROM itn_network', 

 2958, 0.5,

1194, 0.5, 

 false, 

 false

);

Result

Any suggestions on how to debug this?  Using the same two vertices with the
Djikstra functions works fine.

I am running it on Postgresql 9.2.13 64bit with PostGIS 2.1.7 and pgRouting
2.0.0

"POSTGIS="2.1.7 r13414" GEOS="3.4.2-CAPI-1.8.2 r3924" PROJ="Rel. 4.8.0, 6
March 2012" GDAL="GDAL 1.11.1, released 2014/09/24" LIBXML="2.7.8"
LIBJSON="UNKNOWN" TOPOLOGY RASTER"

"2.0.0";"pgrouting-2.0.0";"0";"f26831f";"master";"1.53.0"

Thanks
