Issue Summary

The JET Tool checks for the required field should be only against the issue types selected in the Jet configuration and used by projects that tie the boards.
Since all the field configurations/screen schemes of the project are checked instead of the board related ones, the error below keeps occurring:
{
"type": "error",
"name": "Critical error occurred while checking boards required fields.",
"datetime": "2021-12-03T16:30:38.060Z",
"object": {}
}

Steps to Reproduce

1. Create a project using multiple field configurations/screen schemes
2. Configure one or more issue types with custom required fields
3. Create a Board that is NOT tied to the issue type(s) configured with the custom required fields
4. Run the JET Tool

Expected Results

JET tool check #5 for the required custom field is successful since the board is only tied to the issue type with optional custom fields.

Actual Results

JET tool check #5 for the required custom field fails with the error:
{
"type": "error",
"name": "Critical error occurred while checking boards required fields.",
"datetime": "2021-12-03T16:30:38.060Z",
"object": {}
}

Workaround

Set all the required custom fields to be optional for ALL the field configurations of the project (including the fields configuration of the issue types not tied to the board).
