Azure Blob Storage Images Not Fully Visible in Free Account

Using Labelbox Annotate
1

Hello Labelbox Support Team,

I am currently evaluating Labelbox for potential use in my company and running tests using the free account.

My project focuses on image labeling, specifically object detection and image classification. Due to internal company requirements, I needed to connect an Azure Blob Storage account where all the images are stored. I was able to successfully connect the storage and start labeling images directly from the blob storage, which is working correctly.

However, I am facing an issue where only around 500 images appear available, even though there are thousands of images in the container. I have tried multiple configurations and troubleshooting steps, but without success. At this point, I am unsure whether this is due to a platform limitation of the free plan, a configuration issue, or something I might be doing incorrectly.

I was close to abandoning the evaluation and moving to another platform, but before making that decision, I wanted to reach out to confirm whether this behavior is expected or whether there is a possible solution.

Thank you very much for your time and support. I will be happy to provide any additional information if needed.

Hey @amolina ,
While looking into the dataset silestone-cara-atras, which contains 500 data rows, an “Incorrect CORS Header” error is appearing. This is likely causing the issue you are experiencing.​

Please review and update the CORS settings on your blob storage, then try again.​

Hi,

I updated the CORS settings on my Azure Blob Storage and added the relevant Labelbox URLs. The connection test is now passing successfully.

However, after clicking Sync, not all of the images are appearing in Labelbox. The catalog in Labelbox still shows 492 data rows, but there are more blobs/images in the Azure container:
