ASM Export JSON - size Limit ?

Hello Thanks for you reply,
I ended up at the same conclusion,
F5 Bigip API cannot manage large file and
I needs to upload or download file in 1024kb chunks parts.

Haven't find how to do it with ansible,
so  I did it in shellwith:

    url= "https://{{ inventory_hostname }}/mgmt/tm/asm/file-transfer/downloads/{{ export_filename }}"
    output="{{ export_filename }}"
    taille={{ task_status.json.result.fileSize }}
    chunk=1048576
    debut=0
    fin=1048575
    while [ $debut -lt $taille ]; do
      if [ $fin -ge $taille ]; then
        fin=$(($taille - 1))
      fi
      curl -s -H "Content-Range: $debut-$fin/$chunk" -o /tmp/partie_$debut -H "Content-Type: application/json" -H "X-F5-Auth-Token: {{ extracted_auth_token }}" $url
      debut=$(($debut + $chunk))
      fin=$(($fin + $chunk))
    done
    cat /tmp/partie_* > {{ dest_dir }}/{{ export_filename }}


if someone else have a better way to do it, I'm interrested...
