Application Deployment Failure to Gateway for Applications with Empty Value Attributes when the server restarts

[ShakyaPr]

Description

There is an issue with application deployment to the gateway after restart for applications that were created using empty value attributes.

Expected Behaviour

After creating applications with empty value attributes, and restarting the gateway, the created applications should still be available in the gateway.

Actual Behaviour

Cannot see applications after restart.

Steps to Reproduce

1. Add the following properties to the deployment.toml file

[apim.devportal]
enable_empty_values_in_application_attributes = true

[[apim.devportal.application_attributes]]
required=false
hidden=false
name="Optional attribute"
description="Description of Optional attribute"

[[apim.devportal.application_attributes]]
required=true
hidden=false
default="Default value of Required attribute 1"
name="Required attribute 1"
description="Description of Required attribute 1"

[[apim.devportal.application_attributes]]
required=true
hidden=false
default="Default value of Required attribute 2"
name="Required attribute 2"
description="Description of Required attribute 2"

2. Start the server with Oracle 19c as DB
3. Create two applications and stop the server.
4. Start the server again.
5. Retrieve all the applications deployed in the Gateway using REST API call.
