Issue at hand:
1. I am trying to read firestore data in cloud data fusion using the native adaptor available.
2. When trying to read timestamp datatype and taking it as output it is throwing following error:
3. At firebase dataset, 'created' field has timestamp datatype and when reading data in data fusion output schema datatype is selected as timestamp as well.
Currently working with your case to provide you information of the error message you are getting.
The "created" field has the "Timestamp" type, but according to your settings, it should have the "java.util.date" type.
That "java.util.Date" appears to be a class, so there must be a problem with your configuration.
My other team members faced same issue for different projects, collections and fields. There is a very less chance we all have wrong configuration, it seems more like a bug. Please check again, or suggest me what could I have wrongly configured.
In that case, my suggestion would be to create a PIT (Public Issue Tracker - Cloud Data), or contact Cloud Support so they can review your project to determine the issue.
