This article addresses the "Cloud stack generation failed. Please try generating again" error that can appear when uploading images within the platform. This error is typically triggered by image file issues, upload timing problems, or exceeding system constraints — even when you believe you are within the allowed limits. Follow the steps below to identify and fix the root cause.
🔍 Common Causes
- Unsupported file format or corrupt image: The platform requires standard image formats (JPG, PNG, WebP). Corrupt files or uncommon formats can silently fail during cloud processing.
- File size too large: Even if you have selected fewer than the maximum number of images, an individual file may exceed the per-image size limit.
- Image dimensions out of range: Extremely large or unusually small pixel dimensions can cause the cloud stack to fail during generation.
- Temporary upload or server timeout: A slow connection or a brief platform instability can interrupt the cloud processing step.
- Metadata or EXIF data conflict: Some images carry embedded data that can interfere with cloud stack processing.
🛠️ Step-by-Step
- Check your image file format. Confirm each image you are uploading is saved as JPG, PNG, or WebP. If your file is in HEIC, TIFF, BMP, or another format, convert it to JPG or PNG using any free image converter before re-uploading.
- Check individual file size. Even if you selected fewer than 4 images, verify that each individual file is under 5 MB. Large files can exceed the cloud processing limit on their own. Compress or resize any oversized images before retrying.
- Check image dimensions. Ensure your images are not excessively large (e.g., raw camera exports at 8000×6000 px or higher). Resize to a web-friendly resolution such as 1200×800 px and attempt the upload again.
- Strip image metadata. Use a tool such as Squoosh (squoosh.app) or your operating system's export options to save a clean copy of the image without EXIF metadata, then try uploading the cleaned file.
- Retry the generation. After addressing any file issues, dismiss the error message, re-select your images, and click the generate button again. Wait for the progress indicator to complete fully before navigating away.
- Try a single image first. If the error persists with multiple images, isolate the problem by uploading one image at a time to identify which specific file is causing the failure.
- Clear your browser cache and retry. A stale session can contribute to upload failures. Clear your browser cache, log back in, and attempt the upload in a fresh session or a different supported browser (Chrome or Edge recommended).
✅ How to Confirm It Worked
After retrying, the cloud stack generation is successful when:
- The progress indicator completes without displaying the "Cloud stack generation failed" message.
- Your uploaded image or images appear as previews or thumbnails within the interface where you initiated the upload.
- Any associated content or feature that depends on the image (such as a schema entry or GBP post) shows the image attached and ready to use.
If the error reappears on a specific image even after following all steps above, save the file name, its format, and its size so our team can investigate a potential processing issue on that file type.

Additional Notes
Confirm you are selecting fewer than 4 images — deselect all images and reselect them one at a time to rule out a selection state error in the UI. Also: try a different browser or clear your cache / open in incognito window, as stale cache can interfere with upload processing.
