JSON Exports: Handle error while widgets are deleted

[subinasr]

Problem Description:

When attempting to export JSON data, the export process fails if any widgets have been deleted. The application is unable to handle the scenario where widgets are missing, leading to an incomplete or failed export

Steps to Reproduce:

• Delete one or more widgets from the framework.
• Attempt to export the JSON data.
• Observe that the export process fails or produces incomplete data.

Expected Behavior:

The JSON export should successfully handle scenarios where widgets have been deleted. Ideally, the system should:

• Skip over missing widgets.
• Provide default values or placeholders where necessary.
