Inaccuracy in `module edit` feature

[cx0810]

User guide specifies that n/NEW_MODULE_NAME was not required to be in the input details. However, when attempting to edit a module detail without n/NEW_MODULE_NAME, user is unable to edit the details of a module.

Team's Response

In this case, the module edit you have entered does not change any aspect of the module (same participants) and thus is the same as the old module. That is why the error is thrown as neither the name nor the persons have been changed. This is a feature not a bug.

Items for the Tester to Verify

❓ Issue response

Team chose [response.Rejected]

• I disagree

Reason for disagreement: If no changes are to be made, then the error message displayed should not be as seen in the screenshot, but should instead indicate to users that no changes are detected. The error message currently is misleading for users.
