Problems when export data to JSON file

Hi all!
I have a problem. When I tried to export the data to JSON file, in the process I lost the last lines. I can’t find a way to solve this problem. Does someone have any idea about this that can help me?

I’m working with nodes of lunchbox: Datasets.create dataset and Data Sets.SerializeJSON in dynamo Version 1.3.4

Try updating to a Dynamo 2.0.3 and the newest version of Lunchbox.

In version 2.0x the lunchbox doesn’t have these nodes, for that reason, I’m using version 1.3.4

Ah. Might be a reason they aren’t included. I recommend reaching out to the package author directly.

Thanks for your advice
