Hi woodymoo , Thanks for reaching out to Microsoft Q&A. There are possible reasons for this issue: If public access to your storage account is disabled, you must ensure access by either adding your IP to the storage firewall or enabling access through a virtual network that has a private endpoint connected to the storage account. There are some cases, the account key in datastore is out of sync with the storage account, you can try to update the account key in datastore detail page to fix this. If you're using Azure AI Foundry, the storage account needs to set CORS to allow Azure AI Foundry access the storage account, otherwise, you see the flow missing issue. You can add following CORS settings to the storage account to fix this issue. Go to storage account page, select Resource sharing (CORS) under settings , and select to File service tab.

Azure AI Studio keep getting "Flow is missing" when deploying prompt flow.

Tried to search MS community, but no use.

Is there a detailed log I can analyze?

I'm getting the same issue simply trying to view the prompt flow.

The browse preview is able to successfully connect to the blob storage account, so that rules out any CORS or key issues. The storage account has public access enabled, and access controls look good.

The error in the header is x-ms-error-code: NoAuthenticationInformation

@Shikha Ghildiyal ,

The storage account's networking settings is "Enabled from all networks" for "public network access".

The Azure AI Foundry's UI has been changed. Please verify with the latest UI. I think you refer to updating the credentials for Data source connections. I have filled the account keys to these data source connections. I did same actions for all the data storage connections.

I filled the "Allow Origins" and permissions for the Resource Sharing (CORS)

No Use. The issue is not resolved.

I am having the same issue. Even creating new flows fails. Did anyone get a response from support? Thanks

I am having the same issue, too :(

Upon further investigation, I've noticed that there seems to be a 401 unauthorized error when trying to access Azure Files in my Storage Account. While I can find connection settings for Blob containers in Azure AI Foundry, I'm unable to locate the appropriate settings for Azure Files.

I would appreciate it if someone could answer this.

Thanks

Also having this issue, raising a ticket with support - sounds like a wider Microsoft issue. For those looking to urgently make changes to to their prompt flows, you might be able to access the flows via Visual Studio hosted on a compute within Azure Foundry following these steps:

I also had the same issue. I was just playing and i found a way, so what i did is :

i went to the storage

selected Access Control(IAM)

Add role assignment

I selected Azure Ai administrator

Managed identity

Select Members

All system assigned managed identities

And selected the project & azure search

After this when I go to my azure foundry portal and click my prompt flow, I was able to open it.

I don't think this is best practice, but this seemed to do the trick for me.

et Voila

I tried, but no use.... Opening a technical support ticket, Microsoft will charge me $29, which may not be necessary. The product is not mature and not ready for the market; it is Azure AI Foundry's bug, and it is not an issue of my operations.

I followed your instructions, but it still doesn't work for me. Thanks so much.

I need to avoid this unmatured product until the bug has been fixed.

I also followed your instructions, created a new prompt flow, saved it and now I can access all the prompt flows.
