Translation Framework: cannot get preview file

[thebestusernameifound]

I am trying to get the preview file while using the translation integration framework.

I am using the code provided in the Bootstrap Connector (https://github.com/Adobe-Marketing-Cloud/aem-translation-framework-bootstrap-connector).

Here's the specific code parts:

(in the uploadTranslationObject() function)

		// Generate Preview
		if(isPreviewEnabled) {
			try {
				ZipInputStream zipInputStream = translationObject.getTranslationObjectPreview();
				if (zipInputStream != null) {
					unzipFileFromStream(zipInputStream, previewPath);
				} else {
					log.error("Got null for zipInputStream for " + getObjectPath(translationObject));
				}
			} catch (FileNotFoundException e) {
				log.error(e.getLocalizedMessage(), e);
			} catch (IOException e) {
				log.error(e.getLocalizedMessage(), e);
			}			
		}
		log.trace("Preview Directory is: {}", previewPath);

also

	private static void unzipFileFromStream(ZipInputStream zipInputStream, String targetPath) throws IOException {
		File dirFile = new File(targetPath + File.separator);
		if (!dirFile.exists()) {
			dirFile.mkdirs();
			log.trace("Created directory: {}",dirFile);
		}

		ZipEntry zipEntry = null;
		while (null != (zipEntry = zipInputStream.getNextEntry())) {
			String zipFileName = zipEntry.getName();
			if (zipEntry.isDirectory()) {
				File zipFolder = new File(targetPath + File.separator + zipFileName);
				if (!zipFolder.exists()) {
					zipFolder.mkdirs();
					log.trace("Created directory: {}",zipFolder);
				}
			} else {
				File file = new File(targetPath + File.separator + zipFileName);

				File parent = file.getParentFile();
				if (!parent.exists()) {
					parent.mkdirs();
				}

				FileOutputStream fos = null;
				try {
					fos = new FileOutputStream(file);
				} catch (FileNotFoundException e) {
					log.error(e.getLocalizedMessage(),e);
				}
				int readLen = 0;
				byte buffer[] = new byte[1024];
				while (-1 != (readLen = zipInputStream.read(buffer))) {
					fos.write(buffer, 0, readLen);
				}
				fos.close();
			}
		}
		zipInputStream.close();
	}

I've added some extra logging and it seems the specified folder was created but after checking it in CRXDE there is no such folder.
How this should work? Is there a specific folder where the preview needs to be saved?
Or is it even a working code example?

Thanks in advance!

Can you check what is the value of the "targetPath" parameter? I am wondering if the file is not being generated in the server where AEM is installed and not necessarily in AEM.

I tried with a few paths, none was working. Like saving in tmp folder (/tmp/bootstrap-tms/previews/) or in var (/var/bootstrap-tms/20240119/previews). The bootstrap service has jcr:all permission on these folders.

I meant if the target path is not in the server (OS) paths like: "/mnt/crx" if you are on linux OR "c://somefolder" in windows. Is this an AEM path?

yeah I found it on a server path, thanks for pointing this out, it all works now!
