We get the following error message.  
Does anyone know what this specifically means?

Hi Marco

It looks to us that the error message is because of a temporary error state. The reason might be the order of the configuration sent from the Microgateway Operator to the Microgateway Engine container.

You can ignore this log message if the status of the SidecarGateway CR is ok and the Pod is ready. The following two manual pages provides you more information:

- [Listing the SidecarGateway status](https://docs.airlock.com/microgateway/latest/#data/1662655596907.html)
- [Pod is not ready](https://docs.airlock.com/microgateway/latest/#data/1660804707299.html)

If you want us to investigate this issue further, feel free to open a support ticket.

Kind Regards  
Stefan
