    Hi and welcome to the community,
    First of all let me say how grateful I am that you took the time and introduced yourself.  This always makes it so much more motivating to help others.  In particular, I appreciate that you put so much effort into giving us such a rich background on the data you are working on and what you are trying to achieve.  This is going to be very helpful when I am going now down into my basement, polish the crystal ball, and guess the context in which this error potentially may have been occurring ;)
    This is all to say: can you please share more information with us?  Like the type of data you work on?  When this error occurred?  The process creating it?  What you tried to do?  Without this, it will be very hard to help you.  Which we genuinely want to do.
    All the best,
    Ingo
