The error message you are encountering, "Deployment '' not found under our Application 'IV-*-Agent'", suggests that Azure is unable to find a deployment associated with your application due to an empty deployment name being interpreted. This could be caused by several factors:
- Deployment Name Configuration: Ensure that the deployment name is correctly configured in your application settings. If there have been any recent changes to the configuration, verify that the deployment name is not inadvertently set to an empty string.
- Active Deployment Check: You should check if the deployment for your application is active and correctly registered. This can typically be done through the Azure portal by navigating to your Application and reviewing the Deployments section.
- Resource Provider Registration: If the deployment was previously working and suddenly stopped, it might be worth checking if the required resource providers are still registered. Unregistered providers can lead to deployment issues.
- Intermittent Issues: Sometimes, Azure services may experience intermittent issues. If everything appears correct on your end, consider redeploying or checking Azure service health for any ongoing issues.
If the problem persists, you may need to contact Azure support for further assistance.
