The variable l_proc_name declared as VARCHAR2(100) does not have a valid size since Oracle12.2

[akinet]

The procedures log_internal, log_error, and time_start have the variable l_proc_name declared as VARCHAR2(100). These variables store owner+package_name+procedure_name. Starting with Oracle 12.2, these names can be up to 128 bytes long. Therefore, 100 bytes is insufficient to store this information. l_proc_name must be declared as VARCHAR2(384) to store this information.

In the time_start procedure, it is not necessary to modify this declaration, as this variable is never used within the procedure.
