Query s view causes and exception in some calls

Java SDK
21

Tried version 2.0.2 and got the “cannot decode view json” again.

22

2.1.0-dp seems to address my issue. I’m no longer receiving “Cannot decode view Json” messages.

Thanks for the quick turnaround.

23

@nikkki do you also want to try 2.1.0-dp to see if it solves your issue? Here’s how to get it: http://blog.couchbase.com/n1ql-dp4-java-sdk

@daschl Tried and the result still isn’t good though without “Cannot decode view json” anymore, and I’m running a simple query to the beer sample, using the “brewery_beers” view, on a non-VPC instance from your official community version AMI(3.0.0):

The line 69 in CouchTool.main() is System.out.print("Total_Row:" + Integer.toString(vr.totalRows()) + "/Found_Row:" + Integer.toString(vr.allRows().size()));, and “vr” is a ViewResult.

25

I am also getting this error but intermittently with the stack trace below.

I have the following observations:

  • I don’t believe it has anything to do with the server as when I run the same query against the server 100 times it responds every time correctly.
  • The data that is shown in the stack trace has nothing to do with the view query, the data is from another unrelated document
  • It looks to me as if some requests are being crossed over so that the view query runs but the client reads the response from another request or a chunk from another request

Is there anyone working / looking at this?

@jamesdbloom can you try 2.1.0 which was released yesterday?

27

I just got this same JSON decode error with 2.0.3, tried 2.1.0 which seems to fix the decode error.

28

awesome! great to hear it works
