Airbyte is an open-source data integration engine that helps you consolidate your data in your data warehouses, lakes and databases.

Airbyte

When running Airbyte, many  containers (`airbyte-cron` , `airbyte-connector-builder` , `airbyte-server` ) return following errors:

```main ERROR Error processing element Then ([If: null]): CLASS_NOT_FOUND
main ERROR Error processing element Else ([If: null]): CLASS_NOT_FOUND
main ERROR Error processing element If ([Filters: null]): CLASS_NOT_FOUND
main ERROR Console contains an invalid element or attribute "If"```
I assume I can safely ignore them, can you confirm that?

Hmm, I don't know enough to give you a confident answer yet. The information extracts provided do not contain specific details about the error messages you're encountering. I recommend checking out the [Airbyte documentation](<https://docs.airbyte.com/>) or the [Airbyte community forum](<https://discuss.airbyte.io/>) for more information or to ask for help from the community.

Getting the same errors - was this an issue after all?

I noticed that during the reboot periods the memory reached the limit of the k8s pod. I resized it and the restarts with this same error you reported stopped. I'm using helm version --version=0.49.6
