The file size is zero when using the S3 CopyObject API

I want to use the S3 CopyObject API with Postman. Although the response status is 200, the content-length is 0, and the destination file exists but the file size is zero.

Url: https://<bucket>.s3.<region>.amazonaws.com/<destination-object>.jpg?X-Amz-Copy-Source=<source-folder>/<source-object>.jpg

Other parameter uses Postman authorization and request content-length is 0.

Solution

  • Sorry, I made a mistake. I thought X-Amz-Copy-Source was a query parameter, but it is a header. Changing the query parameter to a header worked for me.
