account.new_batch_order Data sent not valid

[MTenorio-Automation]

I was following the examples to set a new batch order from um_futures and first I got the 3 to 4 arguments error which is already addressed in another issue, and then got the Data sent for parameter '...' is not valid. In the example the batchOrder parameter is handled as a list of dictionaries but this didn't work for me until I converted it to a JSON string. I'm not sure if I missed a step or something, but if not I think the example or the actual method should be fixed.
