Replication progress 0/0

Mobile Couchbase Lite
1

Hi,

We switched from couchDB to couchbase and set up a SQ. Everything seems to work fine until we try to replicate from our Mobile application.

var url = new Uri(“blip://xxxxx:xxxx@10.10.10.18:4984/users”);
var db = new Database(“users”);

    var config = new ReplicatorConfiguration
    (
         db,
         url
    );
  
    var replication = new Replicator(config);
    try
    {
        replication.Start();
    }
    catch (Exception ex)
    {
        var t4 = ex;
    }

It seems to get stuck on the connecting process. Here is the output

There is no abnormal log information from the sync gateway or the couchbase server. Anyone able to read the output info and hand me some tools from here on?

thanks

System.EntryPointNotFoundException: mono_get_runtime_build_info

This looks like some kind of Mono code-loading exception. I’m not very familiar with .NET, but @borrrden should be able to help you with this.

BTW, it’s helpful if you describe what platform/version of Couchbase Lite you’re using, and on what OS.

Yes +1 to what Jens said, although this looks like Xamarin Android. What version are you using because this looks like an API mismatch between Xamarin and the Mono runtime (which is a Xamarin issue). I recommend asking on their forums as well. Basically they call into a runtime method (mono_get_runtime_build_info) that doesn’t exist for whatever reason as part of a standard .NET call to FrameworkDescription. Could you uninstall, clean your project etc too while you are at it?

Another question: What are your linker settings? Apparently Full Linking is associated with this problem sometimes.

Hi guys,

thank you for your replies. We had a Holiday yesterday. I will update Xamarin but also SG and CBL to the latest (preview) versions and will report back.

UPDATE:

linker: set to none
versions:
SG 1.5-494
CBL 2.0.0-db013
Couchbase Server 5.0.0-3217

still the same error

I’ll post on Xamarin.Forms as well… .

Ok guys, very weird. I updated to Visual Studio 15.3 and everything works fine now!

Thanks for your help

Xamarin android is really finicky especially with shared runtime settings. My best guess would be that the shared mono libs ok the device were still the older version that didn’t have that call.
