We have found the root cause of that error. It is failing in one of our components when finishing the pipeline execution when the preview is deployed using the automatic preview environment feature. We are working on a fix and we’ll release it as soon as we can.
This should not affect on your deployment, as this is the last thing of being executed but it could generate some corner cases. if you want to avoid the error, you can use our cli to deploy the preview environment for now, here is the documentation about that command: Okteto CLI | Okteto Documentation
We’ll let you know as soon as the fix is released.
