Based on the error I suspect this is occurring due to tablespace IFSAPP_LOB does not have enough space in the database.

Please try the below query in the database and see if you have enough storage.

select df.tablespace_name "Tablespace",
totalusedspace "Used MB",
(df.totalspace - tu.totalusedspace) "Free MB",
df.totalspace "Total MB",
round(100 * ( (df.totalspace - tu.totalusedspace)/ df.totalspace))
"Pct. Free"
from
(select tablespace_name,
round(sum(bytes) / 1048576) TotalSpace
from dba_data_files 
group by tablespace_name) df,
(select round(sum(bytes)/(1024*1024)) totalusedspace, tablespace_name
from dba_segments 
group by tablespace_name) tu
where df.tablespace_name = tu.tablespace_name

If not enough space there. Please try according to the below post to resolve the issue

SAHAN IS ASKING POLITELY, I WILL NOT THE LOB TABLE SPACE IS OUT OF SPACE/DISK/STORAGE AND NEEDS TO BE EXTENDED.
