This error message usually occurs when you try to access an iterator that points to a position before the beginning of the vector. It can happen when you use an invalid iterator or when you modify the vector while iterating through it.
To fix this error, you need to make sure that your iterator is pointing to a valid position in the vector. You can use the `begin()` and `end()` functions to get valid iterators that point to the first and last elements of the vector.
If you are modifying the vector while iterating through it, you should consider using a different approach, such as iterating through a copy of the vector or using a different data structure that allows for safe modification during iteration.
