07/20/2022, 8:08 AMIn Prefect 2.0, I’m trying to create a Deployment which takes arguments from a configuration stored in Prefect Cloud as a custom block. Here is the sample code:
config = CustomConfig.load('my_block')
Deployment(
name="My deployment",
flow=my_flow,
parameters={
"password": config.password
}
)prefect deployment create my_deployment.pyAttributeError: 'coroutine' object has no attribute 'password'
Failed to load deployments from 'my_deployment.py'
sys:1: RuntimeWarning: coroutine 'Block.load' was never awaiteda

07/20/2022, 11:24 AMthanks @Anna Geller, but I think my situation is different from the example you provided. I know I can save and load blocks within flows, but at the moment I want to create a deployment as described in https://orion-docs.prefect.io/concepts/deployments/#creating-deployments by using the CLI. I’ve supposed that load would also work outside a flow but it looks like it doesn’t. Now I’m trying to create the deployment directly in Python with
Deployment.create()here is the code
if __name__ == '__main__':
config = CustomConfig.load('my_setup')
deployment = Deployment(
name="MyDeployment",
flow=my_flow,
parameters={
"password": config.password,
"slack_webhook": config.slack_webhook }
)
deployment.create()TypeError: Object of type 'AsyncWebhookClient' is not JSON serializableso it looks like Pydantic is failing in serializing the Slack Webhook Block
so at the end I’ve fixed by doing this
if __name__ == '__main__':
config = CustomConfig.load('my_setup')
deployment = Deployment(
name="MyDeployment",
flow=my_flow,
parameters={
"password": config.password,
"slack_webhook": config.slack_webhook.url }
)
deployment.create()nevertheless, it could be handy to be able to quickly inject a block stored in the cloud into a deployment
