What happened?

When the variables from old environment are imported in JSON file via Airflow--> Admin--> Import Variables, it is converting the (") around keys and values both to (')characters. And it is also complaining about the (') character as it is expecting (") characters.

To validate this, added a dag to access all the airflow vars and specifically load the json value to ensure if " to ' conversion is just a UI thing or an actual backend bug. So it looks like the import option is messing up the json value and that would cause an issue when accessing the airflow variable value.
While adding the variable manually from the right hand side option via “Add Variable” button seems to be working fine as of now.

Sample of JSON file:

{
  "test_string": "abcd",
  "test_num": 123,
  "test_bool": true,
  "test_json": {"test_var": "test_val"}
}

What you think should happen instead?
