I’m in the process of upgrading from WSO2 API Manager (APIM) 3.2 to 4.3, and I’m encountering issues with my custom Java mediator. In version 3.2, I used a script to copy my sequences to the /repository/deployment/server/synapse-configs/default/sequences folder. However, this approach doesn’t work in 4.3 because sequences are now handled using a database.
