Chartboost installation failed

I tried to install chartboost plugin to my cocos2d-x project.I have successfully installed iap plugin few days ago.

Can you rerun the install command?

Sometimes install will fail when upgrading sdkbox.

I Installed manual but how can I use chartboost, for example how can I call interstital ad(I am using iap plugin too)? My sdkbox_config.json as following;

{
    "android": {
        
        "Chartboost":{
            "id":"<CHARTBOOST ID>",
            "signature":"<CHARTBOOST SIGNATURE>",
            "ads":{
                "Default":{
                    "type":"interstitial"
                },
                "Level Complete":{
                    "type":"rewarded_video"
                },
                "MoreApp":{
                    "type":"more_app"
                }
            }
        }

        "iap": {
            "items": {
                "remove_ads": {
                    "id": ""
                }
            }, 
            "key": ""
        }
    }, 
    "ios": {
        
        "Chartboost":{
            "id":"<CHARTBOOST ID>",
            "signature":"<CHARTBOOST SIGNATURE>",
            "ads":{
                "Default":{
                    "type":"interstitial"
                },
                "Level Complete":{
                    "type":"rewarded_video"
                },
                "MoreApp":{
                    "type":"more_app"
                }
            }
        }

        "iap": {
            "items": {
                "remove_ads": {
                    "id": ""
                }
            }
        }
    }
}

Console gives this error when I run app on ios simulator.

ERR: SDKBox IAP: failed to get configuration
ERR: Chartboost: Failed to get plugin config json
ERR: SDKBox IAP: failed to get configuration

I checked your json syntax, it seems like there is some mistakes there

Try it using
