Describe the bug

Currently the deployment of a subscription for event-mesh-sap2sap resource fails with error

 Error: API Error Creating Resource Subscription (Subaccount)
│ 
│   with btp_subaccount_subscription.sap2sap_subscribe,
│   on main.tf line 33, in resource "btp_subaccount_subscription" "sap2sap_subscribe":
│   33: resource "btp_subaccount_subscription" "sap2sap_subscribe" {
│ 
│ undefined API error during subscription

Checking the resource in the BTP Cockpit revelas following error

Couldn't subscribe to SAP Cloud Application Event Hub. Please try again. If the problem persists, open a support case using the component: CA-EB.

So i investigated th btp cli using btp get accounts/subscription --subaccount xxxxxx --of-app event-mesh-sap2sap --plan standard and checked the state of the subscription there. This revealed

app name:                                             event-mesh-sap2sap
commercial app name:                                  event-mesh-sap2sap
app id:                                               event-mesh-sap2sap-app!t26928
plan name:                                            standard
supports plan updates:                                false
Whether it supports subscription parameters update:   false
type:                                                 
status:                                               SUBSCRIBE_FAILED
application url:                                      
subscribed tenant id:                                 xxxxxx
subscribed subaccount id:                             xxxxxx
subscription id:                                      
app error:   {"description":"failed to unmarshal SubscriptionContext json"}

This seems to be an issue of the GO BTP Provider unmarshalling a json file obviously.

Expected Behavior

When i create the subscription using the btp cli then it all works fine. So this should also be the case using the BTP Terraform provider.

Steps To Reproduce

1. Execute a terraform init
2. Execute a terraform apply with the following configuration

hcl
resource "random_uuid" "uuid" {}
resource "btp_subaccount" "project" {
  name         = "terraform-test"
  subdomain    = "terraform-test-${random_uuid.uuid.result}"
  region       = lower("eu20")
  usage        = "USED_FOR_PRODUCTION"
  parent_id    = [inclue your parentId here]
  beta_enabled = true
}

resource "btp_subaccount_entitlement" "sap2sap" {
  subaccount_id = btp_subaccount.project.id
  service_name  = "event-mesh-sap2sap"
  plan_name     = "standard"
}

resource "btp_subaccount_subscription" "sap2sap_subscribe" {
  depends_on    = [btp_subaccount_entitlement.sap2sap]
  subaccount_id = btp_subaccount.project.id
  app_name      = "event-mesh-sap2sap"
  plan_name     = "standard"
}

Error could be reproduced. The implementation of the event-mesh-sap2sap app cannot handle an empty JSON file for parameters (in contrast to other subscriptions)

The provisioning of parameter JSON must be relaxed.

In addition, the error message could be improved if saas manager response object returns an app error (as displayed in the cockpit)

@mvk-abs PR #1005 is open and in review. The fix should be available with the next release of the provider (release 1.10.0)
