A few weeks ago, we endup encountering a forbidden issue while trying to deploy a couple of workflows to a brand new Logic App Standard:
Error 403 – Fordidden
In our case, we were using a brand new Logic App Standard with VNet integration.
Cause
This issue typically occurs when you configure your Logic App Standard to use a VNET, and you may have misconfigured or non-existent network-required configurations.
To better troubleshoot whether there was missing network configuration between the developer machine or user permission, we ended up manually creating on the Azure Portal a dummy workflow that receives an HTTP request and simply returns a response—and we were able to do that. So, it was not a user permission.
Next, we use this same POC workflow and try to trigger it from our developer machine using form example, POSTMAN – in this case, we endup getting the same error: 403 Forbidden. That proved that it was indeed a network issue from our developer machine and the Logic App Standard.
Solution
In our case, we contact the infra team, and it was a simple fix:
- They just need to add a firewall rule to allow the developer machine to be able to access.
