[jira] [Commented] (TINKERPOP-2228) by(valueMap(true)) drops all
properties during query
[ https://issues.apache.org/jira/browse/TINKERPOP-2228?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16868474#comment-16868474 ]
stephen mallette commented on TINKERPOP-2228:
---------------------------------------------
I added some tests around this issue and all pass on 3.3.8 and 3.4.3 SNAPSHOTs:
https://github.com/apache/tinkerpop/commit/11b1235410a651ca40407ed71cd5e0a04c5766e8
This may be an issue specific to the graph database you are using. I think that this issue would need to be isolated to TinkerPop in order for us to proceed further with this.

> Key: TINKERPOP-2228
> URL: https://issues.apache.org/jira/browse/TINKERPOP-2228
> Project: TinkerPop
> Issue Type: Bug
> Components: javascript
> Affects Versions: 3.4.1
> Environment: MacOS Mojave 10.14.4
> Reporter: Byron Bailey
> Priority: Major
>
> When using the by(valueMap(true)) step when using the gremlin javascript plugin, a result set is returned but the properties are all missing. The same query works from the console. Additionally, the same query without by(valueMap(true)) returns a valid result set.
>
> Below is the sample code with the output, along with the same query against the same graph using the console. The test case is a simple server architecture with a "host" node having three edges connecting it to 2 "vm" nodes and a chassis node. I have also tried the identical query using client.submit() and receive failed results.
>
> {code:java}
> const g = traversal().withRemote(new DriverRemoteConnection('ws://localhost:8182/gremlin'));{{}}
> const __ = gremlin.process.statics;
>
> function getNeighbors(label, uuid){
> console.log("> getNeighbors "+label+"["+uuid+"]");
>
> return g.V()
> .has(label,"uuid",uuid)
> .bothE()
> .otherV()
> .path()
> .by(__.valueMap(true))
> .toList()
> }
> getNeighbors("host", "host1")
> .then(results => {{{ }}
> console.log("Sending results..."+JSON.stringify(results));
> });
> {code}
> OUTPUT:
> {code:java}
> > getNeighbors host[host1]
> Sending results...[{"labels":[[],[],[]],"objects":[{},{},{}]},{"labels":[[],[],[]],"objects":[{},{},{}]},{"labels":[[],[],[]],"objects":[{},{},{}]}]
> {code}
>
> Same query from console:
> {code:java}
> gremlin> g.V().has("host","uuid","host1").bothE().otherV().path().by(valueMap(true)).toList()
> ==>path[
> {id=1, label=host, model=[D-host], manufacturer=[Dell], name=[host1], uuid=[host1]}, {id=0, label=MOUNTED_IN, uuid=6ca30477-80e2-4df6-9e00-10adddc0c04f, name=host1 to chassis1, slots=1}, {id=0, label=chassis, model=[D-chassis], manufacturer=[Dell], name=[chassis1], uuid=[chassis1]}]
> ==>path[{id=1, label=host, model=[D-host], manufacturer=[Dell], name=[host1], uuid=[host1]}
> , {id=20, label=MOUNTED_IN, uuid=ea0b7e49-9738-4624-86e7-ba57de873120, name=vm1 to host1},
> {id=22, label=vm, name=[vm1], uuid=[vm1]}
> ]
> ==>path[
> {id=1, label=host, model=[D-host], manufacturer=[Dell], name=[host1], uuid=[host1]}
> , {id=16, label=MOUNTED_IN, uuid=966ad71a-ad09-4877-93b2-14779edf3ba9, name=vm2 to host1},
> {id=21, label=vm, name=[vm2], uuid=[vm2]}
> ]
> {code}
>
> If I remove the .by(__.valueMap(true)) from the javascript query, I receive the following valid output:
>
> {code:java}
> > getNeighbors host[host1]
> Sending results...[{"labels":[[],[],[]],"objects":[
> {"id":1,"label":"host"}
> ,{"id":0,"label":"MOUNTED_IN","outV":1,"inV":0,"properties":{}},{"id":0,"label":"chassis"}]},{"labels":[[],[],[]],"objects":[
> {"id":1,"label":"host"}
> ,{"id":20,"label":"MOUNTED_IN","outV":22,"inV":1,"properties":{}},{"id":22,"label":"vm"}]},{"labels":[[],[],[]],"objects":[
> {"id":1,"label":"host"}
> ,{"id":16,"label":"MOUNTED_IN","outV":21,"inV":1,"properties":{}},{"id":21,"label":"vm"}]}]
