Create a new storage account and Blob container
If you already have an existing storage account or blob container, you can skip this step.
- Create a new storage account
- Create a blob container inside your storage account. Be sure to set the "Public access level" to
Private, to ensure that your source maps are not publicly accessible.
Push your source maps to your Blob container
You should integrate your continuous deployment pipeline with your storage account by configuring it to automatically upload your source maps to the configured Blob container. You should not upload your source maps to a subfolder in the Blob container; currently the source map will only be fetched from the root folder.
Upload source maps via Azure Pipelines (recommended)
If you are using Azure Pipelines to continuously build and deploy your application, add an Azure File Copy task to your pipeline to automatically upload your source maps.

Required role-based access control (RBAC) settings on your Blob container
Any user on the Portal using this feature must be at least assigned as a Storage Blob Data Reader to your Blob container. You must assign this role to anyone else that will be using the source maps through this feature.
Depending on how the container was created, this may not have been automatically assigned to you or your team.
Source map not found
- Verify that the corresponding source map is uploaded to the correct blob container
- For example,
/static/js/main.4e2ca5fa.chunk.jswill search for the blob named

- Check your browser's console to see if any errors are being logged. Include this in any support ticket.
