Azure AD B2C doesn't log to application insight

Question

Azure AD B2C doesn't log to application insight

Frode Blænes 1

Hi,

We have two instances of Azure AD B2C running the same custom policies. However one of our instances doesn't log anything to Application Insight.
The only differences when it comes to the application insight flow is DeploymentMode is set to Production and DeveloperMode is false in the instance that that doesn't log properly. They both log to separate application insights.

I've tried changing both of those variables without any success. I have also tried using the Instrumentation Key from another Application insight and it won't log to that one either.

Please let me know if any more information required.

Thanks.

Hi @Frode Blænes - did you have any luck with this? I'm getting exactly the same issue.

Changed the DeploymentMode to Development and DeveloperMode to true, and after a while starts logging. Seems it doesn't log anything to AI with prod settings.

Hello @Frode Blænes ,

Thanks for your time and patience. Could you please validate the following:

If both Azure B2C instance are part of same Resource Group.
If both are different then validate, Azure Application Insights is linked to a Log Analytic Workspace that belonged to same Resource Group as your Production B2C instance.
Try creating a new instance

Let me know if you have any queries in the comments section.

Hello,
The B2C instances are in different resource groups.
The Application insights and the connected Log analytics are in the same resource group as the B2C instances.

I've tried making a new Application Insight in the same resource group as the production B2C instance and there still are no logs for this B2C instance in that application insight after changing the Instrumentation Key to the new one in our custom policy.
