My goal: read a secret value from Azure key vault in Azure function app
Steps:
Azure key vault side:

• Generated secret
• Access control (IAM)>Add role assignment: gave role Reader to my function
• Secret>Version>Enabled, copy secret identifier
  Azure function app side:
• Settings>Identity>System assigned: Status=On, Permissions: Reader to my key vault.
• Configuration>New application settings: name=<name of secret>, value=<secret identifier as copied from key vault, of the form @Microsoft.KeyVault(SecretUri={https://myvaultabc.vault.azure.net/secrets/...})
• Save, refresh: Error: Could not access key vault reference metadata.

Any help appreciated.
Thanks.

Answer 1

@arunabhabhattacharya-3120 I think you are using curly braces "{" in your application settings which is not required. You need to remove curly braces in you Key Vault reference . Key Vault reference would be like below -

 @Microsoft.KeyVault(SecretUri=https://myvault.vault.azure.net/secrets/mysecret/dc85f01090234f109d13b2e92cdb3431)

Please let me know if you this works else provide more details like, code snippet, application configuration screenshots to help you better. I also suggest you to refer to documentation which provides details of accessing secrets from Azure functions.
