In any case, I am pretty sure this is happening because the "x", "y", and "z" fields get written automatically and so when you specify them, it is trying to write them twice. This is definitely a bug and should be easily fixed, but in the mean time you should be able to get around this by removing those fields from your field list.</div><span class="HOEnZb"><font color="#888888"><div><br></div><div>Britton </div></font></span></div><div class="HOEnZb"><div class="h5"><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Sep 22, 2017 at 10:18 AM, Nathan Goldbaum <span dir="ltr"><<a href="mailto:nathan12343@gmail.com" target="_blank">nathan12343@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div dir="auto">Hi Jose,</div><div dir="auto"><br></div><div dir="auto">This feels like a bug.</div><div dir="auto"><br></div><div dir="auto">Any chance you can make a runnable example that triggers this error?
