  4. identifiedDec 15, 2025, 15:10 UTC

    We are currently working to resolve a reported issue when using both Strict Transformations and the Auto-Upload feature. Until we resolve the issue, you may see "Transformation ... is not allowed" errors on requests that should trigger an auto upload from a remote URL or bucket. Until we resolve the issue, you can work around the issue by temporarily disabling Strict Transformations or using another method to allow the transformation to proceed such as signing the URL or adding an Strict Referral Domain: https://cloudinary.com/documentation/control_access_to_media#strict_transformations
