Hi I m running into a few issues while trying to use Prefect Prefect Community #ask-community

Hi, I'm running into a few issues while trying to use Prefect 2.0 block storage. I'm receiving a CORS error in Chrome when I try to delete a block in the UI at app.prefect.cloud. I have no issue creating block storage through the UI or through Python.

Copy code

Access to XMLHttpRequest at '<https://api.prefect.cloud/api/accounts/><MY ACCOUNT ID>/workspaces/<MY WORKSPACE ID>/block_documents/<MY BLOCK ID>' from origin '<https://app.prefect.cloud>' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

It seems like CORS may be unhappy with the UI trying to do a cross-domain request from app.prefect.cloud to api.prefect.cloud?

Also when I try to build a deployment with

prefect deployment build -n test -t download_dataset -sb RemoteFileSystem/wasabi test-flow.py:download_job

I receive this error

Client error '404 Not Found' for url '<https://api.prefect.cloud/api/accounts/><MY ACCOUNT ID>/workspaces/<MY WORKSPACE ID>/block_types/slug/RemoteFileSystem/block_documents/name/wasabi?include_secrets=true'

. I'm able to interact with Prefect cloud from the CLI otherwise.

My goal is to use a RemoteFileSystem block for persistent storage in a Wasabi S3 bucket. I had this working in a previous version of the Prefect 2.0 cloud beta before Deployment Create was deprecated.

I've read these docs initially. The issue I'm experiencing is that the

prefect deployment build

command cannot find the directory where my block storage is located when providing the

-sb

argument. I'm certain I'm logged into the Prefect Cloud correctly because I'm able to list the resources I've created.

Looks like someone fixed the CORS issue. I'm thinking

RemoteFileSystem

may not be a valid

block_type_slug

Hey Andrew, struggled myself, found out 😄 The slug for remote file system is remote-file-system, if I recall correctly
