@Marvin when loading a block in a Jupyter cell, I get 'coroutine' object has no attribute 'data' error. This has something to do with the prefect block load method being an async method. How do I get around it and actually instantiate the block with the block.load method in a Jupyter cell.

Ah, technology! It seems there's a bit of a snag with my tools right now, so let's take a stab at solving this issue sans digital assistance. When you encounter the
'coroutine' object has no attribute 'data'
error in a Jupyter cell, it's because you're trying to use an asynchronous function (async) in a synchronous environment. In Python, methods like
block.load
that are asynchronous need to be awaited. Here’s a workaround: you can run the code in an event loop using
asyncio
, which allows you to run asynchronous code in Jupyter:
Copy code
python
import asyncio
from prefect.blocks.core import Block

async def load_block():
    block = await Block.load("block-name")
    return block

block = asyncio.run(load_block())
Replace
"block-name"
with the actual name or identifier of your block. This should allow you to properly instantiate and use the block in your Jupyter notebook without running into that pesky error. If you have further questions about async and await in Python, feel free to ask!
