Data Hub: All integration keys are null

[former_member1208351]

I'm trying to export data on a test system, but I encounter the same issue for each item: all data attribute are null, leading to an invalid_promary_key on my canonical.

Output in datahub log:

 2018-03-26 14:24:53,863 [INFO] [c.h.d.s.i.DefaultRawTypeComposerService] 96 items found for composition of type UnitRaw
 2018-03-26 14:24:54,203 [DEBUG] [c.h.d.c.i.CompositionChainRunnerStrategy] Integration Key generation for canonical item CanonicalItem{id='null', integrationKey='null', status=ERROR, dataPool='DataHubPoolEntity{id=3, name=pool}', batchId=null, traceId=null, uuid=null, documentId=null, fields='{unitType=null, name_fr=, code=null, name_de=, name_it=, conversion=null, name_en=}'} failed.

Note: It works perfecty in my local system (localhost)

fixed, I had an erro in my impex: INSERT_UPDATE Y2YColumnDefinition; position[unique = true]; my position was not starting by 0 but 1...

another mandatory field :in my impex:

 INSERT_UPDATE Y2YColumnDefinition; position[unique = true]; attributeDescriptor(enclosingType(code), qualifier); impexHeader; StreamConfiguration(StreamId)[unique = true]; columnName; language(isocode)

columnName must be filled, was not the case before....

Better to merge this answer with your old / original answer. :)
