Bug

• Which version of SkyWalking, OS and JRE?
  6.2.0、windows 10 1903、build 1.8.0_171-b11

• Which company or project?

• What happen?
  If possible, provide a way for reproducing the error. e.g. demo application, component version.

I ran _C:\xxx\apache-skywalking-apm-binbin\startup.bat_ then ran my project with vm args with _-javaagent:C:\xxx\apache-skywalking-apm-bin\agent\skywalking-agent.jar=agent.service_name=service-a_ in sts4.3. Then I visited http://localhost:8080/, none of graphs were shown, chrome network showed that two responses with the body

{
    "errors": [{
        "message": "Invalid Syntax"
    }]
} 

which request payload is

{
    "query": "query queryData() {}",
    "variables": {
        "serviceId": "3",
        "endpointId": "",
        "endpointName": "",
        "instanceId": "3",
        "databaseId": "",
        "duration": {
            "start": "2019-07-05 1047",
            "end": "2019-07-05 1102",
            "step": "MINUTE"
        }
    }
}

and the skywalking-oap-server.log recorded that

2019-07-05 11:32:57,661 - graphql.GraphQL - 507 [qtp1502668485-54] WARN  [] - Query failed to parse : 'query queryData() {}'

You need to check oap log.

[wu-sheng]

Set up the env at local with h2 by following quick start. Then dive into more complex way.

[wu-sheng]

First, check service and endpoint numbers on UI.

Do I have to configure anything before running startup.bat ?
Quick start says that

Storage, use H2 by default, in order to make sure, don't need further deployment.

And version 6.1.0 is fine as what I did in 6.2.0

First, check service and endpoint numbers on UI.

The dashboard bar shows right info including optional services, endpoints and instances.
The trace page is able to show requests as well.

I used the 6.2.0 webapp and the 6.2.0 oap , I'm got the same result, but I used 6.1.0 webapp, 6.2.0 oap, it's working for me.

[wu-sheng]

You need to delete all indexes when uograde to 6.2.0. We indicate it clearly in changlog.

[wu-sheng]

For UI 6.1.0, I don't believe it is working for 6.2.0. We changed the topology query API, how is possible it still working?

I did't use ES, the storage implement is h2 by default.

[zengxiaowengit]

hello, guys, when I use docker image apache/skywalking-oap-server:6.2.0 and the same version skywalking-ui, Storage, use H2 by default, it's also no any graph and /grahql result is:

• message: "Invalid Syntax".

how did you resolve this problem?
thanks.

[wu-sheng]

Are you using OLD UI?

[zengxiaowengit]

I'm using these docker version:

apache/skywalking-oap-server:6.2.0
apache/skywalking-ui:6.2.0

, is this wrong?

[tedinGH]

Are you using OLD UI?

No.I tried it on rhel, the same package was working fine although it seems like a little bit delayed for minutes on registration.

[wu-sheng]

Register is async mode.

[zengxiaowengit]

@wu-sheng I have tested serveral times with 6.2.0, but this problem didn't change at all.
I meet this 2 problems in oap server. one warning and an runtimeException.
thanks.

[wu-sheng]

ID can't be NULL is not related to any feature. We explain a lot of times.

[zengxiaowengit]

@wu-sheng
may be It's because I use spring cloud gateway in my project. although I just directly test the service api, gateway also post the trace data into oap server. when I add the optional-plugins/apm-spring-cloud-gateway-2.x-plugin-6.2.0.jar into my microservice agent plugin directory, now I can see chart in Topology and Trace menu, but can't see chart in Dashboard.

• What I can do with this situation?

Thanks.

[wu-sheng]

If you can see in topo, there should have been in dashboard. From my understanding.

[MoDann]

Me too, both topology and track have chart, only the dashboard has no chart，graphql response is

{"errors":[{"message":"Invalid Syntax"}]}

[zengxiaowengit]

Yes. I also meet the same questions. what frameworks do you use? springboot OR spring cloud webflux?
we can check it together.

[MoDann]

I am using SpringBoot. The previous local and personal server testing is no problem, the test environment on the emergence of such problems.

[wu-sheng]

Check time and time zone settings. Many users miss that reminder at the first line of setup document.
