Adobe campaign classic try to store base64 data into schema via webapp but getting error on webapp

Hi Team,

In ACC v7, I am trying to upload image and video files (JPEG/MP4) by generating Base64 data and storing it in the schema.

The process works fine for image files, but when I try to upload a video file, it does not work. I am currently using the web app for this.

Could you please help me understand what might be causing this issue and suggest a possible solution?

its give me error like this :

WEB-530007 Error relaying '/webApp/getBase64Data' to URL 'http://localhost:8080/webApp/getBase64Data?_uuid=ertf-4567-0987-2345-42kh986C86k8&_lastModified=2026-05-05%2005:29:50.183Z&_debug&lang='.

Regards,
