Configuring oauth2_credentials in kong.yaml gives error 'kong uniqueness violation oauth2'

We are adding OAuth2 credentials in our kong.yaml file for Kong version 3.4. Our current configuration is as follows:

consumers:
  - id: consumer_id
    username: consumer_username
    custom_id: consumer_custom_id

oauth2_credentials:
  - redirect_uris:
      - https://www.example.com/test
    consumer: consumer_id
    id: credential_id
    name: credential_name
    client_secret: client_secret
    client_id: client_id

However, this configuration does not work in Kong 3.4. We encounter the following error:
“In entry 1 of oauth2_credentials ‘client_id’: uniqueness violation”

How can we resolve this issue in Kong 3.4?
We have already check that no client_id is availabe in cache, as well as there are no duplicate client_ids

This configuration worked in Kong 2, so we implemented it similarly in Kong 3.4.
