Hi Jacqueline,
Not sure if this is why you're receiving the error message but I had this
error when asking pgstar to plot a variable on an incompatible graph. So if
you've included a custom history_columns.list or profiles_columns.list in
your project directory. Check to see if you have pgstar attempting to plot
a non standard history or profile variable as it may not be compatible with
the graph in which you are trying to plot it. Doesn't seem like it could
cause an issue but for me once I adjusted my pgstar section, it was
resolved and I no longer received the error.
Hope this helps.
Regards,
Carl
