default value will be removed while add linker to target node

[Anonymous]

I am using Talend Open Studio for Big Data Version: 6.1.1 with Talend Connector/tCouchbaseOutput, and I want to import data from csv file to couchabse.
and When I Generate JSON Document Configure JSON Tree, I can not set a Fix value for a target property when I add linker  to target node.
Before I add linker to target node, I can set Fix value for the target property,but when I add linker to target node, the default value is removed. And at the same time,the "set Fix value" is disable.
And after I import data to Couchbase, the empty value in csv will be ``` [] ``` in Couchbase.

Hi,

Could you please show us your input source? What does the expected Json tree look like?
Best regards
