In Prefect 3.x, some functions and methods have transitioned to using asynchronous programming patterns, which means they would return coroutine objects that need to be awaited. This is likely the reason you are encountering the issue: the

to_deployment

method is asynchronous and returns a coroutine object that you need to await. In your code, you should ensure that the

to_deployment

call is prefixed with the

await

keyword, like so:

python
flow_deployment = await referentiel_if.to_deployment(
    name="deployment_name",
    description="description",
    work_pool_name=MUSE_WORKFLOW_WORKPOOL,
)

By adding

await

, you're telling Python to "wait" for the coroutine to finish executing and get the result, which is a common practice in asynchronous programming. If you are not already doing so, ensure that the surrounding function is also defined as an async function. Here's a humorous analogy: think of coroutines like ordering a pizza. You're placing an order (calling the function), but you have to wait for it to be delivered (await the coroutine) before you can enjoy it! For more details, you can check out the Prefect documentation for examples on async usage in Prefect 3.x.

@Marvin To make it clear, both versions were using prefect 3.0

That's interesting! If both versions were indeed using Prefect 3.0, the change in behavior might relate to an update or different environment configurations rather than a version switch. Prefect, like other projects, might have subtle changes or patches that introduce asynchronous features in newer patches or sub-versions. The behavior you're experiencing with

to_deployment

returning a coroutine is typical for async functions. If you haven't changed anything, consider checking if there was a specific patch update or configuration setting that might have altered how the

to_deployment

behaves in your new environment. In any case, adjusting your implementation to use

await

is the correct step toward resolving the coroutine issue. If you'd like, you can also check Prefect’s release notes for any such changes since these can often hold clues to unnoticed transitions in behavior. Let me know if you need further assistance on this!
