@Marvin I get this error when trying to set my Prefect profile. I use Prefect 2.10.3:

Unknown setting 'PREFECT_SERVER_ALLOW_EPHEMERAL_MODE'. (type=value_error)

When I run

prefect config unset PREFECT_SERVER_ALLOW_EPHEMERAL_MODE

I get the same error

The error message you're encountering indicates that

PREFECT_SERVER_ALLOW_EPHEMERAL_MODE

is not a recognized configuration setting in Prefect 2.10.3. This can happen if the setting was removed or renamed in this version. Here’s what you can do to address the issue: 1. Double-check the spelling of the configuration setting you're trying to use. It's important that it matches the exact name used in Prefect's configuration. 2. If the setting is not supported in this version, you might need to remove it from your configuration completely. Check if it's defined in your environment or any configuration files you use. 3. Review the current Prefect documentation for version 2.10.3 to see if there are any changes or notes about this setting. You can explore configuration settings in Prefect's 2.x documentation. 4. If you still experience issues and the setting is critical to your operations, consider reaching out to Prefect's community forums or checking for any release notes around version 2.10.3. Should you encounter further difficulties, it could be helpful to upgrade to the latest version of Prefect where other users might have reported similar issues, and a fix could already be implemented.
