Hi,
The error message is

error reading odate: odate = 2019-8-15_18:00:00

Your namelist has the following:

 start_date = '2019-8-1_00:00:00','2019-8-1_00:00:00',
 end_date   = '2019-8-15_18:00:00','2019-8-15_18:00:00',

The ungrib program expects a double-digit month and day syntax, so you just need to modify the namelist to

 start_date = '2019-08-01_00:00:00','2019-08-01_00:00:00',
 end_date   = '2019-08-15_18:00:00','2019-08-15_18:00:00',
