Weird Behavior after a series of calls

Hello, I’m facing a weird behavior of the Uppy.XHRUpload component.

I have a simple code that upload a series of images one at a time, the code is the following

function UploadImages() {
	var files = fileUploader.getFiles();

	fileUploader.setMeta({ __RequestVerificationToken: $("input[name=__RequestVerificationToken]").val() });

	if (files.length > 0) {
		fileUploader.use(Uppy.XHRUpload, {
			endpoint: '/{0}/propertyimages/submit/{1}'.format(countryRoute, idProperty),
			timeout: 0,
			fieldName: 'propertyImage',
			limit: 1,
			validateStatus: function (statusCode, responseText, response) {
				return jQuery.parseJSON(responseText).Success;
			}
		});

		fileUploader.on('complete', (result) => {
			if (result.failed != null && result.failed.lenght > 0)
				ShowWarningNotification(ValidationResources.Error_PropertySubmittedTitle, ValidationResources.Error_PropertySubmittedMessage);

			ShowFinalStep();
		});

		fileUploader.upload();
	}
	else {
		ShowFinalStep();
	}
}

After a series of calls (randomly) the component changes the behavior from an XHR call to a multipart/form-data without apparent reason and this makes all the following calls to fail.

Here the screenshot of the calls: https://ibb.co/nCfstLZ

Any reason for this behavior?

Thanks, at the end was a problem of the token that I was passing to the page not of the upload! Solved so!
