The symptom observed on this issue are errors referencing a property not defined similar to the example below:

Resolution
To identify the property which causing this issue, use the API to query the properties of the existing staged products. This will allow to identify the product that persisted an incorrect value.

• Obtain the list of staged products:
  •  All staged products: https://developer.broadcom.com/xapis/tanzu-operations-manager-api/latest/api/v0/staged/products/get/
    • curl -H 'Authorization: <value>' https://{api_host}/api/v0/staged/products

 

• Review the properties for each staged product:
  • Getting A staged product's properties: https://developer.broadcom.com/xapis/tanzu-operations-manager-api/latest/api/v0/staged/products/product_guid/properties/get/
    • curl -H 'Authorization: <value>' https://{api_host}/api/v0/staged/products/{product_guid}/properties

 

• To review the properties for the BOSH Director tile:
  • Getting A staged director's properties: https://developer.broadcom.com/xapis/tanzu-operations-manager-api/latest/api/v0/staged/director/properties/get/
    

    • curl -H 'Authorization: <value>' https://{api_host}/api/v0/staged/director/properties

The product with the incorrect values will error out or return ActionController::Parameters somewhere in the response. Once the property with the incorrect value is identified the customer can modify it to the correct format.

Below is an example of how an invalid format can look:

## property value with incorrect format:
 .cloud_controller.encrypt_key:
   value:
     secret:
       secret: MYPASSWORD
 
 
 ## correct format for the property
 .cloud_controller.encrypt_key:
   value:
     secret: MYPASSWORD
