Hosted Model Deployment Troubleshooting

Async Errors

Due to the async nature of Azure Deployments, sometimes the Azure APIs return a successful response, even though the component has not completed initialising in the background. This means that the deployment script may attempt to make changes to a recently created component that is not ready yet.

The errors below are all examples of errors in this category. This will only happen during the initial install of the ProcessFactorial Any subsequent deployments will only deploy updated binaries and the occasional new component, so this should not happen after the initial install.

If these errors occur, simply rerun the deployment script. It will validate the deployment and continue.

Cannot convert 'System.Object[]' to the type

This happens during the initial create of the APIM instance. Simply restarting the deployment will resolve this
