Please set no limit to buffer size for session.
DBMS_OUTPUT. ENABLE (buffer_size => NULL);
Then please retry.
Buffer size is session dependent.

You might consider a few options. You can reduce output size; perhaps this will work. Alternatively, you can follow these two options: pagination or chunking, or increase buffer size.
