Getting Error while applying leave through Mobile App and Waring while applying through the Desktop.

We are currently developing the Mobile App for HCM, utilizing API to replicate the Fusion Process. However, we have encountered an issue that requires your assistance.

Case Overview:

When attempting to apply for leave with a Unit of Measure (UOM) in hours, the front-loaded value is set at 80 hours. Once all these hours are availed and we try to create an absence for a specific employee, we receive a warning message, as documented in the attached file.

However, when we attempt the same process using the mobile app, a different error occurs, which is also detailed in the attached document. Notably, the message codes differ between Fusion and the mobile app.
