Oracle Apex - HTTP ERROR 200 Service Unavailable

In Oracle 20.2, there is an upload file that ends up to this error after attempting to upload a huge file (1.8GB). This huge file was taking 1 hour to load and ends up to this error. Please refer to ss below:

I first thought it was because the default session was 1 hour, so after 1 hour I thought it would stop the session and cause that error, so I increased the sessions up to 2 days: please refer to ss below:

Tried to upload that same huge file (1.8GB) and now it gets this new error.

Any idea what is causing this? Was increasing the session just right or should I revert it back to default?

Any ideas or suggestions are appreciated!

    Settings of the file upload has 2 processes which are as follows:

    1. Process: Process Row of FILE_TRANSFER_T

    2. Import Collection (PLSQL)





        apex_debug.message('file_id : '||:P200_FILE_ID);

        EXECUTE IMMEDIATE('alter session disable parallel dml');


            p_file_id => :P200_FILE_ID


        apex_debug.message('Collection succeeded');


      when others then

      apex_debug.message('Collection failed with '||sqlerrm);

    There are also timeout settings in ORDS - maybe ORDS isn't getting the response from APEX and then decides to throw the 200?

    Maybe you can try splitting this into two actions/pages - one to upload the file and another to do the processing? I would guess that the processing is taking all the time. The processing could be kicked off in background so that there's no browser/ORDS/APEX time-outs to consider.
