Issue Summary

When there are no mapped statuses (on Column management of board configuration), accessing the control chart report throws a Javascript error.

This javascript error is considered misleading by the customer as it's not a user-friendly error message.

Steps to Reproduce

1. On the board, go to board configuration > column management.
2. Move statuses to unmapped column
3. Access control chart report

Expected Results

It will throw an error message on the requirement of the mapped status in a human-understandable error message.

For example:
"There is no mapped status on this board. Requirement: at least one status to be mapped onto the configured columns"

Actual Results

The below exception is thrown in the screen:

Exception: Uncaught TypeError: Cannot read properties of undefined (reading 'toString')
