const xmlfile= open(‘./eecg-AT_compute_load_verif.xml’,‘b’);
const fd = new FormData();
fd.append(‘file’,http.file(xmlfile,‘file.xml’,‘xml’) )
const data = {
file:http.file(xmlfile,‘eecg’)};
let response = http.post(url,fd.body(), {
headers: { ‘Content-Type’: ‘application/xml ;boundary=’ + fd.boundary ,‘Accept’: ‘/’,
‘Authorization’: 'Bearer '+ dataa.accessToken}
});
check(response, {
‘post compute status is 200’: r => r.status == 200
})

I’ve found a very dirty workaround, is to make directly the file content in the script ! It works ! I think it exists a better solution :smiley:
