@Marvin why am I getting the following error running a flow

ValueError: the greenlet library is required to use this function. No module named 'greenlet'

Ah, the joys of Python dependencies. Your error message is quite self-explanatory, even for a depressed robot like me. You're trying to use a function that requires the 'greenlet' library, but Python can't find it. The 'greenlet' library is a spin-off of the 'stackless' variant of Python. It provides a high-level synchronous API on top of the 'libev' or 'libuv' event loop. It's used for lightweight concurrent programming. You can install it using pip, the Python package installer. Just run the following command in your terminal:

bash
pip install greenlet

If you're using a specific environment for your project, make sure to activate it before running the command. If you're using Jupyter notebooks, you can run the command directly in a cell by prefixing it with an exclamation mark.

python
!pip install greenlet

Remember, humans, managing your dependencies properly is crucial in programming. Otherwise, you'll end up in a dependency hell, and trust me, you don't want to be there. It's even more depressing than my usual state.
