Power Pages flows in Power Automate may start displaying an error message after updating connection references. The error message states: "Request to Azure Resource Manager failed with error: 'Could not find any valid connection for connection reference name 'shared_' in APIM header.'" This issue arises when developers create a flow without access to the "common" connection reference added to the solution. To resolve this, navigate to the Power Pages portal, go to the Cloud Flows area, and remove the flows that have started to fail. Then, re-add them. This workaround seems to resolve the error.
