Azure Key Vault References

Hi onerbreno 

If your Fabric notebook isn't fetching secrets with mssparkutils.credentials.getSecret(), here are a few troubleshooting stesps to look out for:

• Make sure your Fabric workspace's managed identity has both the Key Vault Reader and Key Vault Secrets User roles assigned in Azure Key Vault's "Access Control (IAM)".
• Verify the Key Vault name and secret name in your code — they are case-sensitive. Even minor typos can cause silent failures.
• Check that the secret is active — not disabled or expired.
• If your Key Vault uses private endpoints or has public access fully disabled, Fabric won’t be able to reach it. Fabric currently doesn’t support connecting to Key Vaults through private endpoints.
• This code will only work inside a Fabric notebook — it won’t function in an external IDE or local script.
• To confirm which identity your notebook is using to call the Key Vault, run:
          from notebookutils import mssparkutils
          print(mssparkutils.credentials.getIdentityName()
  Let me know if you need help checking any of these or interpreting what you find!
