It's difficult to quote an image ... it seems posting images it's the new black these days.

In any case I didn't know that ta-lib had safediv parameters and in any case the exception catcher you have is non-relevant. Things are lazily evaluated and you get to the evaluated result in next

I suggest you look at the RSI code to see how to handle potential div by zero.

Although your real problem is data variability which no code can fix.
