YAML unmarshal error cannot unmarshal !!str ` ` to str

I am trying to push my Spring Boot application on Pivotal Cloud Foundry (PCF) via manifest.yml file.

While pushing the app i am getting the following error:

{ 
Pushing from manifest to org mastercard_connect / space developer-sandbox as e069875...

Using manifest file C:\Sayli\Workspace\PCF\healthwatch-api\healthwatch-api\manifest.yml

yaml: unmarshal errors:

line 6: cannot unmarshal !!str `healthw...` into []string
FAILED }

Here is the manifest.yml file:

{applications:
- name: health-watch-api

memory: 2GB

instances: 1

paths: healthwatch-api-jar\target\healthwatch-api-jar-0.0.1-SNAPSHOT.jar

services: healthwatch-api-database 
  }

Your manifest is not valid. The link @K.AJ posted is a good reference.

https://docs.cloudfoundry.org/devguide/deploy-apps/manifest.html

Here's an example, which uses the values from your file.

---
applications:
- name: health-watch-api
  memory: 2G
  path: healthwatch-api-jar/target/healthwatch-api-jar-0.0.1-SNAPSHOT.jar
  services:
  - healthwatch-api-database

You don't need the leading/trailing { }'s, it's path not paths and services is an array. I think the last one is what the cli is complaining about the most.

Hope that helps!
