ListSecrets not working on .NET 8 isolated functions running on a dedicated plan

Annelotte Mons 25

Recently upgraded a .NET 6 functions project to .NET 8 isolated worker model. Turns out this breaks our deployments which are using the "listSecrets()" functionality to get the function keys. When looking in the portal its working fine on a reference to it, but the listSecrets on it fails with an error message stating Function Not Found.

The functions themselves seem to work just fine in Azure on the dedicated plan. So I'm a bit puzzled that this functionality isn't working?

@Annelotte Mons Thanks for reaching out. When you mentioned that it breaks your deployment which are using the "listSecrets()" functionality to get the function keys so looks like you are referring to ARM template deployment where you are leveraging the listSecrets to get the function secret? Please correct me if I understand it correctly.

In case if it is ARM template and you have references/depended on resources then you need to make sure that you are dependsOn as in scenario where your resource us not created and you are referring it to some other resources you may see this error.

Correct it is in a subsequent deployment of a Logic App Standard in this case, where we are using the listSecrets functionality to get the function keys.

Dependencies are set in order and the functions all exist (no typos either). I'm also using reference() functionality on the same functions to retrieve the URL which works and does not result in the 404's as compared to the listSecrets.
This setup was/is also working prior to upgrading to .NET8 isolated (coming from .NET 6), making me believe it's an issue with the isolated workers model.

Accepted answer

@Annelotte Mons Thanks for confirmation.

Can you please update the listSecrets to listkeys in your ARM template and see if it helps you to resolve the issue.

I see a previous discussion here where the team recommended to use ListKeys instead of ListSecrets as you shouldn't be used anymore.

Let me know if you still face the issue after leveraging the listkeys method in your ARM template.
