Custom HTTPRequestHandler for public file upload - wakanda

Question

I'm trying to add a HTTPRequestHandler for a public file upload service to wakanda server. Anybody should be able to POST a file to this service without logging in. Unfortunately I get a "403 Forbidden" error on all POST requests made to the HTTPRequestHandler? GET requests work fine but do not not help much in this case ;-)
The intention is to receive the file, process it, and send it back to the client.
Added my request handler as follows:
application.addHttpRequestHandler('^/fileUpload$', './backend/httpRequestHandler/file-upload.js', 'fileUpload');
Any help on how to solve this problem would be much appreciated.

Finally got it to work myself with cURL. Looks like there was some issue with my Postman setup.
cURL command:
curl --form "fileupload=#test.xml" http://localhost:8081/fileUpload
HTTPRequestHandler:
/**
* file upload handler
* #param request {HTTPRequest} http request
* #param response {HTTPResponse} http response
*/
function fileUpload(request, response) {
try {
var counter = 1;
var nameTemp;
var files = [];
var uploadFolder = Folder('/PROJECT/database/data/tmp/');
var result = [];
var newName;
var myBinaryStream;
// create upload folder if not existing
if (!uploadFolder.exists) {
uploadFolder.create();
}
// create file instances
for (var i = 0; i < request.parts.length; i++) {
files.push(new File(uploadFolder.path + request.parts[i].fileName.replace(/\s/g, '_')));
// create result object
result[i] = {};
result[i].name = request.parts[i].fileName;
result[i].type = request.parts[i].mediaType;
result[i].size = request.parts[i].size;
}
// write file content
for (var i = 0; i < files.length; i++) {
counter = 1;
if (!files[i].exists) {
myBinaryStream = BinaryStream(files[i], 'Write');
myBinaryStream.putBlob(request.parts[i].asBlob);
myBinaryStream.close();
} else {
while (files[i].exists) {
nameTemp = files[i].name.replace(/\s/g, '_');
files[i] = new File(uploadFolder.path + files[i].nameNoExt.replace(/\s/g, '_') + counter + '.' + files[i].extension);
newName = files[i].name;
if (files[i].exists) {
files[i] = new File(uploadFolder.path + nameTemp);
}
counter++;
}
myBinaryStream = BinaryStream(files[i], 'Write');
myBinaryStream.putBlob(request.parts[i].asBlob);
myBinaryStream.close();
result[i].name = newName;
}
}
result = JSON.stringify(result);
// add response header
response.contentType = 'application/json';
return result;
} catch (e) {
console.log(e.stack);
return e;
}
}
