Question

Open Cost giving an error to download the price list

Issue Summary

We are experiencing an issue with OpenCost in our Azure Kubernetes Service (AKS) cluster. After enabling OpenCost using the command az aks update --resource-group <resource-group> --name <cluster-name> --enable-cost-analysis, the OpenCost pod is throwing an error related to pricing data download from the Azure API.

Error Message

The error message indicates a failure to refresh the token for the pricing data request due to multiple user-assigned identities existing in the subscription. The specific error is:

"Error in pricing download query from API...  Failed to download pricing data: azure.BearerAuthorizer#WithAuthorization: Failed to refresh the Token for request to https://management.azure.com/subscriptions//providers/Microsoft.Commerce/RateCard?...  StatusCode=400 -- Original Error: adal: Refresh request failed. Status Code = '400'.  Response body: {"error":"invalid_request","error_description":"Multiple user assigned identities exist, please specify the clientId / resourceId of the identity in the token request"}

Hello Kartik,

Welcome to the Microsoft Community. Reviewing the error message, it seems the issue is related to multiple identities and that you need to specify a clientid or resource id. When you tried to enable OpenCost did you specify either of these? If so which one, did you specify?

Typically to resolve this issue, you can try the following steps:

Specify the clientId or resourceId: When enabling OpenCost, make sure to specify the clientId or resourceId of the user-assigned identity that should be used for the token request.

Check your user-assigned identities: Ensure that the user-assigned identities in your subscription are correctly configured and have the necessary permissions to access the pricing data.

As mentioned in we have just ran the "az aks update --resource-group <resource-group> --name <cluster-name> --enable-cost-analysis" not performed or added other information
