Nested json output from neptune-export is not a valid json

[triggan]

Moving this issue here from the older neptune tools repo: awslabs/amazon-neptune-tools#207

I'm trying to export a fairly complex query which has all node and edge properties. The output from the neptune-export service is a json, but it seems like the nested data is not a valid json. Instead, it is separated by "=" instead of ":". Example here. Is this something that can be addressed?

I was able to recreate this issue with the following export-pg-from-queries command:

➜  neptune-export git:(develop) ✗ java -jar neptune-export-2.0.2-all.jar export-pg-from-queries \ 
    -e "neptunedbcluster-xxxxxxxxxx.cluster-xxxxxxxxxx.us-west-2.neptune.amazonaws.com" \
    -q "g.V().has('name','Kevin Bacon').project('node','edge_details').by(valueMap(true).fold()).by(bothE().valueMap(true).fold())" \
    -o stdout -d ./ --region us-west-2 --use-iam-auth --format json 

Returns the output formatted as:

{"node":["{label=Artist, birthYear=[1958], id=nm0000102, name=[Kevin Bacon], newprop=[new]}"],
"edge_details":[
    "{label=actor, id=tt0112453-actor-nm0000102}",
    "{label=actor, id=tt0099582-actor-nm0000102}",
    "{label=actor, id=tt1878841-actor-nm0000102}",
    "{label=actor, id=tt0373450-actor-nm0000102}",
    ....]}
{"node":["{label=Artist, id=nm9323132, name=[Kevin Bacon], newprop=[new]}"],
    "edge_details":["{label=actor, id=tt7470112-actor-nm9323132}"]}
