Blob not found

[ChromaticPanic]

I'm getting a bob not found error

[ "Datastore Error retrieving the picture : The specified blob does not exist.\nRequestId:628986d5-601e-0060-7c8d-fdb62e000000\nTime:2024-09-02T23:10:16.3300199Z\nErrorCode:BlobNotFound\nContent: <?xml version=\"1.0\" encoding=\"utf-8\"?>BlobNotFoundThe specified blob does not exist.\nRequestId:628986d5-601e-0060-7c8d-fdb62e000000\nTime:2024-09-02T23:10:16.3300199Z\nError getting blob:6835a15d-655a-478d-a9d4-c6bdb9230621/9b186422-0650-4b1a-87ed-521c57cedad8.png" ]

using these parameters { "user_id": "a427278e-28df-428f-8937-ddeeef44e72f", "container_name": "6835a15d-655a-478d-a9d4-c6bdb9230621", "picture_id": "9b186422-0650-4b1a-87ed-521c57cedad8" }

I'm guessing from this line 446 in app.py of nachet backend

        container_name = data.get("container_name")
        user_id = data.get("user_id")
        picture_id = data.get("picture_id")

        if user_id and picture_id:

@Francois-Werbrouck What do you think is causing this? I don't have access to blob storage so not sure if doesn't exist or if there is a bug in the datastore module

You can try running this branch, it displays the contents of the folders on the frontend https://github.com/ai-cfia/nachet-frontend/pull/188

Sorry for the delay. I'm unsure what is causing this I could try to directly search the DB to find if these exists.

More details on what the prior operations were before receiving this error would also help narrowing the scope of where to look for this issue. @ChromaticPanic

I'll take a deeper look into this soon

Thanks! Those values were from the get directory API. So I was surprised to get the error.

I'm attempting to use the get-directory api return values to retrieve images to display on the frontend.
