[RaghavMundhada]

Did you get this working ?
I am using
spring boot version: 2.0.5.RELEASE
spring-data-gremlin version: 2.1.2

and getting the same error

[mingjinc]

Can not work.
Waiting for the response..

[Incarnation-p-lee]

@RaghavMundhada
spring-data-gremlin version: 2.1.2 is for spring boot 2.1.x.

@mingjinc
We will try to reproduce this from our env.

[mingjinc]

@Incarnation-p-lee any updates on that? or could u provide me some other spring-data-gremlin/spring-boot compatible version i could try?

[Incarnation-p-lee]

@mingjinc
Sorry for late response, Could you please share more configuration for your code ? as well as the backend db you are using. Looks cannot reproduce your issue from my env.

I am also building a POC for our use case where I experience the issue as well. Please let me know if I can/should provide any other information that might help resolve this issue.

[Incarnation-p-lee]

you can follow this config

[georgschmidtdumont]

Thanks for the quick response.

I am using the following config:

gremlin:
  endpoint: localhost
  port: 8182
  #username: your-username
  #password: your-password
  #sslEnabled: false
  #telemetryAllowed: true

I do not believe that the config is the problem since the connection to the Gremlin server is established successfully.
When I remove line 79 from Application.java, where the Network is saved, the application starts successfully and no errors occur (see console output below).

[Incarnation-p-lee]

I am sorry, line 79 of Application.java is ?

[georgschmidtdumont]

In line 79 of Application.java the Network Entity is saved.

this.networkRepo.save(this.network);

[Incarnation-p-lee]

OK. I see, may enhance the sample later. Thank a lot.

[mingjinc]

@Incarnation-p-lee i think i find the reason.

1. our db is janusgraph, it does not support @id as String type. can this library support if we do not provide @id ? Did this library verified in Janusgraph? How could I resolve this issue?
2. Another one is that could we do transaction control if using this library? for example, we have multiple repositories to do different operation, but we need them in one transaction. As there has no annotation to support it? any other way to do it? like manually start and commit, close.

thx
