The error message you're seeing is related to the replication method configuration in Airbyte. It seems like the configuration is not valid according to the JSON schema. The error message indicates that the

replication_method

should be valid to one and only one of the schema, but more than one are valid. This could be due to a misconfiguration in your settings. The

replication_method

can be either "Standard" or "Logical Replication (CDC)". The "Standard" method requires no setup on the DB side but will not be able to represent deletions incrementally. On the other hand, the "Logical Replication (CDC)" method uses the Binlog to detect inserts, updates, and deletes, and needs to be configured on the source database itself. The error message also indicates that a string was found where an object was expected for the

replication_method

. This suggests that the value provided for this setting might not be in the correct format. Unfortunately, without more information about your specific configuration, it's hard to provide a more specific solution. I would recommend checking your configuration settings related to the

replication_method

and ensuring they match the expected format as per the [Airbyte documentation](https://docs.airbyte.com/). If you continue to encounter issues, you might find it helpful to reach out to the Airbyte community on [Slack](https://slack.airbyte.com/) for more specific troubleshooting assistance.
