java.lang.NullPointerException: Cannot invoke "java.io.Writer.append(java.lang.CharSequence)" because "output" is null" #9

Hello, For me yourTUVU file named Turkey-Vulture-Acopian-Center-USA-GPS-flagged-newUplift-Dec2013.csv produces an error when loaded into the program. The other provided csv file seems to work fine (e.g., albatross-normal-tracks-9track-tailcrosswind.csv) but the 2020 version has the same error (albatross-normal-tracks-9track-tailcrosswind-2020.csv)

I get the same error when I try to load my own data file. I have to fix/match the date format in the process but then when it starts reading again I get the same error as when I try to load your TUVU data set. My goal is to produce something similar to the albatross example you provide where wind support and vectors are shown along with bird movement. Do you have this albatross data set I can use as a test?

The error I get is: "Individual.local.identifier found Location.long found location.lat found study.local.timestamp found Timestamp format: yyyy-MM-dd HH:mm:ss.SSS Something bad happened: java.lang.NullPointerException: Cannot invoke "java.io.Writer.append(java.lang.CharSequence)" because "output" is null"

I'm on a Windows operation system: Edition Windows 10 Business Version 21H1 Installed on ‎2/‎26/‎2021 OS build 19043.1586 Experience Windows Feature Experience Pack 120.2212.4170.0

My Java is version "15.0.2" 2021-01-19

@jongsomjit is this still an issue for you? I'm unable to reproduce
