Issues while configuring the API Subscription BPS WSO2

Question

So, i've my WSO2 BPS 3.6.0 configured to support SSL and a custom hostname i.e. mydomain.domain.com:9445 etc. and i'm trying to implement the API Subscription Workflow by following this documentation.

Now i've performed the following steps:

set the offset of wso2 bps to 2 and it is running fine with port: 9445
edited the wsa:Address tag in bothSubscriptionService.epr and SubscriptionCallbackService.epr located in API-M_HOME/business-processes/epr as the bps server had a customized hostname instead of localhost (not sure if performing this step was right)

SubscriptionService.epr SubscriptionCallBackService.epr
copy-pasted the epr folder from API-M_HOME/business-processes/epr to BPS_HOME/repository/conf/epr
Added the required BPEL package and human task accordingly
Navigated to the carbon console from APIM and edited the workflow-extensions.xml, here's how it looks like
set the TaskCoordinationEnabled tag of b4p-cordination-config.xml to true located in BPS_Home\repository\conf

Consider OTHER required configurations:

At API Manager End:

site.json file located at APIM_Home\repository\deployment\server\jaggeryapps\admin\site\conf

{
  "theme": {
    "base": "wso2",
    "subtheme": "modern"
  },
  "context": "/admin",
  "request_url": "READ_FROM_REQUEST",
  "tasksPerPage": 10,
  "allowedPermission": "/permission/admin/manage/apim_admin",
  "workflows": {
     "workFlowServerURL": "https://mydomain.domain.com:9445/services/",
  },
  "ssoConfiguration": {
    "enabled": "false",
    "issuer": "API_WORKFLOW_ADMIN",
    "identityProviderURL": "https://localhost:9443/samlsso",
    "keyStorePassword": "",
    "identityAlias": "",
    "keyStoreName": "",
    "verifyAssertionValidityPeriod": "true",
    "audienceRestrictionsEnabled": "true",
    "responseSigningEnabled": "true",
    "assertionSigningEnabled": "true",
    "assertionEncryptionEnabled": "false",
    "idpInit" : "false",
    "idpInitSSOURL" : "https://localhost:9443/samlsso?spEntityID=API_WORKFLOW_ADMIN",
    "externalLogoutPage" : "https://localhost:9443/samlsso?slo=true"
  },
  "reverseProxy": {
    "enabled": false,
    // values true , false , "auto" - will look for  X-Forwarded-* headers
    "host": "sample.proxydomain.com",
    // If reverse proxy do not have a domain name use IP
    "context": ""
    //"regContext":"" // Use only if different path is used for registry
  }
}

the workflowconfiguration in api-manager.xml

At BPS end:

carbon.xml

Issue: Now whenever a user navigates to APIM Store and subscribes to any API, the subscription request is listed at the APIM Admin console. When i select APPROVE from the provided ddl and click on the COMPLETE button, the record vanishes. However, this is the error that i see at WSO2's CMD windows:

What could be the issue here? Any idea? do let me know. Thanks

Note that the bps workflow for API STATE CHANGE works just fine with the same configurations
