Hello everyone,
the REST endpoint for receiving the information about the stored data in the
data lake ("../datalake/info") is currently serializing the class
'DataLakeMeasure' (org.apache.streampipes.rest.impl.datalake.DataLakeMeasure)
in JSON, but it should be JSONLD.
I tried to change the serialization, but it does not work. I always get the
error:
"No identifier was found for
[org.apache.streampipes.model.datalake.DataLakeMeasure@3165a907]! The instance
should implement Identifiable, have one or more properties annotated with
@RdfId, or have an id function provided to the mapper.".
The 'DataLakeMeasure' extends the 'UnnamedStreamPipesEntity'
(org.apache.streampipes.model.base.UnnamedStreamPipesEntity), which has a
propertety annotated with @RdfId.
Someone has an idea, what could be the problem? See Branch [STREAMPIPES-79]
Regards
Johannes
