Error "Invalid authentication token format [] []" even when the api key is correct

[danhngo-lx]

Hello, I'm running Whatsapp business api on-premise on a K8s cluster. There're liveness checks that call the endpoint /v1/health of the pod. However even when the authentication header is used correctly and the response is a 200 response, there're these errors in the logs of the pod Invalid authentication token format [] [].
The full logs of the request:

The error is confusing. Is there any way to get rid of it?
