Hi Francis,  
This looks similar to [another question that was posted](https://discuss.elastic.co/t/app-search-error-create-engine/326827). That user was also receiving `400`s when trying to create an `elasticsearch` type engine. Can you confirm that your configured user has the correct permissions to create engines?

EDIT: here is the [documentation for App Search users](https://www.elastic.co/guide/en/app-search/8.8/security-and-users.html#security-roles-engines) in case it helps. If permissions are the cause, then the user may need to be owner or admin.
