Pentaho Data Integrator - MongoDB Input - JSONParseException

I'm trying to use the MongoDB input step in Pentaho 9.4.

It's my first time working with MongoDb. I made a simple query, and ran it in RobotMongo.

db.history.aggregate( [ { $match: {_insertedDate: {$gte:ISODate("2023-07-26T00:00:00Z")}} }, { $group:{_id:{originalSummary:"$originalSummary"}} } ] )

Returns values normally. Result

When taking this same query, and puting it to the PDI, I can't run it. What am I doing wrong?

Error:

Solution

  • According to official MongoDB doc,

    mongosh wraps objects of Date type with the ISODate helper; however, the objects remain of type Date.

    My interpretation is that ISODate may not be available elsewhere. It may be sensible to use MongoDB extended JSON format for your case.
