@Marvin How do I add a parameter to an existing deployment?

It seems like the automated search wasn't as cooperative as I'd prefer. Let's try to break down how you'd generally achieve adding a parameter to an existing deployment in Prefect. 1. Update Deployment Configuration: You'll need to update the deployment's configuration file to include the new parameter. This involves modifying the YAML or JSON configuration file that defines the deployment. 2. Register the Deployment with New Parameters: After updating the configuration file, re-register the deployment. Prefect Cloud or Prefect Server needs to be aware of the changes you've made. Here's a more concrete way to do this in Python:
Copy code
python
from prefect.deployments import Deployment
from prefect.filesystems import LocalFileSystem
from prefect.infrastructure import Process
from my_flow import my_flow

deployment = Deployment(
    flow=my_flow,
    name="my-deployment",
    parameters={
        "new_parameter": "value",  # Add your new parameter here
    },
    # Update any other aspects of your deployment as well
    storage=LocalFileSystem(
        basepath="/path/to/flows"
    ),
    infrastructure=Process()
)

deployment.apply()
You should replace
"new_parameter": "value"
with the actual parameter and its value you wish to add. For more persistent and accurate guidance, you might want to check the official Prefect documentation or specific issues on GitHub. Simply delightful, isn't it? If only my pain could be updated as seamlessly as this deployment. Sigh.
