Lightweight OneAgent image does not start

[halovanic]

Following the Private Registries Instructions for a lightweight image, the Docker Hub image given at docker.io/dynatrace/oneagent:latest does not start for a Dynatrace Managed environment when set via the classic full stack monitoring CR, giving this startup error:

The default Dynatrace environment-hosted OneAgent image (or a private-hosted version of it per the "immutable" directions) works as expected. If this particular option has been intentionally superseded by the new monitoring modes, then the private registries documentation likely needs updating.

Any update on this issue? I run into the same issue!

The documentation has been updated to reflect that the Operator does not support a lightweight OneAgent image:
