Guoliang Sun commented on KYLIN-6018:
-------------------------------------
h3. Root Cause
Previously, there was an issue in the model renaming logic where, if the
`description` was not passed or was passed as `null`, it would automatically be
replaced with an empty string, causing the model's description to be
unintentionally altered.
h3. Dev Design
For the model renaming API, adjust the behavior so that when the `description`
is not provided or is passed as `null`, it means the model's description should
remain unchanged.
> When renaming a model, the description information field is incorrectly
> modified
