mmh that is quite strange… notice how the second closing quote is missing in your JSON?
can you trace the request/response or reproduce it in curl?
does it remotely look like the JSON you’d expect from this view?
I found that this exception occurred if the key contain }
The version of client is Couchbase-Java-Client-2.2.0
In file com.couchbase.client.java.transcoder.JsonTranscoder.java line 99:
int length = input.readableBytes();
return a false value when it found }, and the use this wrong length to call JacksonTransformers.MAPPER.readValue(inputBytes, offset, length, clazz)
Thanks for the additional info, this is indeed a bug.
I’ve opened https://issues.couchbase.com/browse/JVMCBC-263 to track it, I’ll get to it tomorrow and that should be fixed in 2.2.2.
Hi @simonbasle & @jiuchang2004
Is this issue fixed ?
Unfortunately we are still facing this issue when the document contains open/closing curl braces {}.
We have a encrypted content in one of the fields of the document and which may contain curl braces {}.
When retrieving this document we are facing the below error.
Any help is appreciated, thank you!

It was fixed quite a long time ago.
Are you able to reproduce this consistently? If so, can you run a test with logging turned up to TRACE/FINEST and point us to the output? Also, verify the log doesn’t show any issues at the server side if you can.
Thanks for your reply @ingenthr.
With 2.5.4 version this seems to be working fine.
I will see different combinations and keep the forum posted on this.
