Service n1ql not available

Shlomo_Shs · April 26, 2020, 11:29am

Hi,
I downloaded last master version of .net SDK 3.0 client to use the dependency injection option that not available for SDK version 3.0. I compiled and published both projects (Couchbase & Couchbase.Extensions.DependencyInjection).
When I use the Couchbase (without using Couchbase.Extensions.DependencyInjection) I get error on Query:
message=" Service n1ql not available".
When i am using the published version of couchbase-net-client it’s working.
The code quit simple:
var cluster = await Cluster.ConnectAsync(“couchbase://1xx.x6.7x.1x”, clusterOptions);
var bucket = await cluster.BucketAsync(“BucketName”);
var collection = bucket.DefaultCollection();
var qry = $@“select c.* from BucketName as c where type = ‘contact’
and c.timestamp >= ‘{DateTime.Now.AddDays(-30)}’ order by c.timestamp;”;
var results = await cluster.QueryAsync(qry, new Couchbase.Query.QueryOptions()).ConfigureAwait(false);

Can’t understand why?

@Shlomo_Shs - it could be related to this bug or this forum issue. We’ll look into it and see what we find.

I’m on version 3.0.1 from nuget and I’m still having this issue…

jmorris · May 19, 2020, 10:10pm

@coreyponsv -

Can you post logs?

coreyponsv · May 19, 2020, 10:18pm

@jmorris I’d be happy to, which log files are helpful for this?

jmorris · May 19, 2020, 10:25pm

@coreyponsv -

Install Serilog.Extensions.Logging.File and then:

 IServiceCollection serviceCollection = new ServiceCollection();
 serviceCollection.AddLogging(builder => builder.AddFilter(level => level >= LogLevel.Debug) );

 var loggerFactory = serviceCollection.BuildServiceProvider().GetService<ILoggerFactory>();
 loggerFactory.AddFile("Logs/myapp-{Date}.txt", LogLevel.Debug);

 var clusterOptions = new ClusterOptions().WithCredentials("user", "password").WithLogging(loggerFactory);

That should write the sdk log to file.

@jmorris Thanks for that, for some reason I was thinking couchbase log files

Anyway this is what I’ve got:

This might be related, although you seemed to connect and run through server negotiation later.

Couchbase is running locally - same server as app?
Can you confirm that the Query service is running on the cluster you are connecting to?

-Jeff

coreyponsv · May 19, 2020, 10:56pm

That’s correct, I’m running couchbase on my dev box alongside the app with the connection string as “couchbase://127.0.0.1”, I’ve also tried “couchbase://localhost” with the same results, in both instances I can see this same log message

There was an error attempting to resolve hosts using DNS-SRV - “Non-Existent Domain” (9daf8ee2)

I can run queries through the UI with the Query Workbench without any issue and as far as I understand the query service would have to be running for that to work, correct?

In case it is relevant, I’m running the 6.0.1 version of Couchbase and not the latest.

jmorris · May 20, 2020, 12:00am

@coreyponsv -

Yeah, should be working then. Perhaps its a bug with 6.0.1 and a local instance?

-Jeff

coreyponsv · May 20, 2020, 4:30pm

I installed the newest version of couchbase locally, it looks like this query is now working, although I have a little concern that it won’t work in our deployed environments as they are also on 6.0.1.

Thanks for your help @jmorris

shaig4 · December 18, 2020, 2:39pm

i had same problem and eventually it was by mistake i passed 0 (zero) as the KVConnectTimeout.
annoying when an error is unrelated to the actual problem

Robert_Mirabelle · April 5, 2022, 7:19pm

I get this message when doing Cluster.ConnectAsync using an invalid user name or password. Obviously, the error message: Couchbase.ServiceNotAvailableException: Service n1ql not available. is EXTREMELY unhelpful in this context.

How are we supposed to detect when authentication fails?
