[Azure AI Search] Internal Server Error when creating CMK encrypted objects

This article is contributed. See the original author and article here.

Scenario

Customers follow the Microsoft doc to create CMK encrypted objects (data source, index etc.), but get the 500 Internal Server Error:

{‘error’:{‘code’:”,’message’:’Could not use key vault key to wrap/unwrap the encryption key. {‘Message’:’An error has occurred.’}’}

Possible Causes

• The key vault host is incorrect, e.g. incorrect key vault domain.
  
  
  
  • Action: check the keyVaultUri in the Json payload.
  
  
  
  


• The key vault host is inaccessible to search. For example, the key vault has public network access disabled but does not have a shared private link (SPL) configured from search. 
  
  
  
  • Action: check the SPL configurations or create a SPL. 
  
  
  
  

Note that if the key vault Uri is correct or accessible, the error message due to a wrong key vault key name or version in the JSON payload is slightly different. The error message has the complete key vault key path.

{
“error”: {
“code”: “”,
“message”: “Could not use key vault key https://keyvaultname.vault.azure.net:443/keys/wrongkeyname to wrap/unwrap the encryption key. The key vault key cannot be found.”
}
}
