NPE when using the putMarkLogic Processor #14

Closed scarton closed 3 years ago

scarton commented 6 years ago

Using the getFile processor as input, and routing the success path to putMarkLogic, I get the exception below. I provided screenshots of the configuration below. I can provide more details if needed.

I have found that you will always get a NullPointerException if you don't add at least one collection in your PutMarkLogic processor properties (4th one down). I think this is a bug but a descriptive collection name isn't the worst addition to your data anyway :-)

Thanks - and I agree. Was just trying to get this working to test a processor I'm developing that will feed data into it. I'll add a collection name for now until there's a fix.

Verified that this is no longer an issue in 1.9.1.5-SNAPSHOT - was able to use PutMarkLogic on a variety of inputs without any collections being set.
