Hi. I am new to Orekit. I am getting this error while trying to do orbit determination. Kindly note that I am implementing orekit in Python. I initially thought that it was due to the small number of points. I increased the points 10-fold I am still getting the same problem. I appreciate your help.

JavaError: <super: <class ‘JavaError’>, >
