Issue Summary:

When attempting to set a null value for the Forge object type, a validation error occurs: "The value must be a JSON object." This error occurs because the null value is being converted to the string "null."

Steps to Reproduce

1. Deploy the forge app to a test instance and create a custom field of type forge object.
2. Create a custom field from the object type and associate it with a screen.
3. Now, go to the GIC screen -> select null value -> click on the submit button; it fails with the JSON validation error.

Expected Results

null values should be not be converted to string and allowed to submit the null value on GIC.

Actual Results

The JSON validation error is shown on the screen.

The value must be a JSON object

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
