whatsapp business api giving error wacore not instantiated

Currently i am working on whatsapp business api setup using docker . I have followed the instructions specified in installation document.

Installation done successfully and all containers are running fine. When i am performing the health check getting the below response

{     "health": {         "192.168.99.124:337e5a74fec8": {             "gateway_status": "unregistered",             "role": "primary_master"         },         "192.168.99.125:f6d56ce7a303": {             "errors": [                 {                     "code": 1011,                     "title": "Service not ready",                     "details": "Wacore is not instantiated. Please check wacore log for details."                 }             ]         },         "192.168.99.125:f18358cd1dff": {             "errors": [                 {                     "code": 1011,                     "title": "Service not ready",                     "details": "Wacore is not instantiated. Please check wacore log for details."                 }             ]         }     },     "meta": {         "version": "v2.25.5",         "api_status": "stable"     } } 

Two of the core containers (master and wacore) not getting instantiated. i verified my containers, all are running .

Does any one faced this issue ? or this one is the normal because response always giving 200 status code .
