spatial = neo4j-spatial-0.13-neo4j-2.1.2-server-plugin

while adding layer with REST API, getting below exception: Creating new layer 'geoindex_venues' unless it already exists 13:34:49.466 [qtp22441773-51] WARN o.e.jetty.servlet.ServletHandler - /db/data/index/node/ java.util.NoSuchElementException: More than one element in org.neo4j.cypher.internal.compiler.v2_1.PipeExecutionResult$$anon$1@46935c97.

It seems that you have multiple root reference nodes for the spatial extension. The extension however expects to find just one reference node as entry point. To verify this theory check if you get more than one result

MATCH (n:ReferenceNode) RETURN n

If so, you need to check with of the trees underneath the reference nodes is the correct one and drop out all others recursively.
