BLOB for large binary data, model won't load in Polystore #75
Description
After updating our model to include a blob for large binary data in mongo and mariadb it is not possible to load the model in the polystore, the typhon-polystore-service application fails just after retrieving the polystore conf from mongo, with the error below.
If we replace the addModels.js with the one previously generated WITHOUT the blob and we just re-create the containsers with
docker-compose down -v
docker-compose up polystore-mongo
docker-compose up typhon-polystore-service
then it works.
is there something wrong in our model?
find attached:
-
the model which works along with its .js, WITHOUT the blob. NOTE: the JS was generated with an older version of the plugins
-
the model WITHOUT the blob and the JS generated with the new plugin. it does not work, it produces the same error as the one with the blob (below)
-
the model WITH the blob, generated with the new plugins, and the log of the polystore service when it is started
attached file:

"_old_JS" means the JS was generated with older plugins"
"_new_JS" meand the JS was generated with current pluging:
