Compress PDF file in Google Script

How to compress a pdf file in a Google Script ?

I already use convertapi to merge pdf files, successfuly. But I try, unsuccessfuly, to compress the final pdf file

Code OK for MERGE

var file = DriveApp.getFileById(idPDF1);
formData['Files[' + index + ']'] = file.getBlob();
index++;


var options = {
'method' : 'post',
'payload' : formData,
'muteHttpExceptions': true
};

var global_pdf_name = nom_fichier + " - " + dateJour + ".pdf";
var response_glob = UrlFetchApp.fetch('https://v2.convertapi.com/pdf/to/merge?Secret=XXXXXXXXXX', options);
if(response_glob.getResponseCode() == 200) {
var contentText = JSON.parse(response_glob.getContentText());
var blob_glob = Utilities.base64Decode(contentText.Files[0].FileData);
var link_fact = destination.createFile(Utilities.newBlob(blob_glob, 'application/pdf', global_pdf_name));

// Code NOK for COMPRESS

    var formDataC = {};
    var fileC = DriveApp.getFileById(id_mergepdf);
    formDataC['File'] = fileC;
    var options = {
    'method' : 'post',
    'data' : formDataC,
    'muteHttpExceptions': false,
    'processData': false
    };

    var global_pdf_compresse = nom_fichier + " - " + dateJour + ".pdf";
    var response_globC = UrlFetchApp.fetch('https://v2.convertapi.com/convert/pdf/to/compress?Secret=XXXXXX', options);
    if(response_globC.getResponseCode() == 200) {
    var contentTextC = JSON.parse(response_globC.getContentText());
    var blob_globC = Utilities.base64Decode(contentTextC.Files[0].FileData);
    var link_factC = destination.createFile(Utilities.newBlob(blob_globC, 'application/pdf', global_pdf_compresse));

// Error message in the trace

How about this modification?

Modified script:

From: 
var fileC = DriveApp.getFileById(id_mergepdf);
formDataC['File'] = fileC;
var options = {
'method' : 'post',
'data' : formDataC,
'muteHttpExceptions': false,
'processData': false
};
To: 
var fileC = DriveApp.getFileById(id_mergepdf).getBlob(); // Modified
formDataC['File'] = fileC;
var options = {
'method' : 'post',
'payload' : formDataC, // Modified
};

If I misunderstood your question and this was not the result you want, I apologize.
