Hey,

I’m using @aws-sdk/s3-presigned-post with node js to generate presigned urls that I use to upload images on the client side.

I’m able to add metadata fields like content-type and x-amz-meta-help but for some reason not content-disposition.

This is some of the code I use to generate the presigned url:

const { url, fields } = await createPresignedPost(client, {
  Bucket: bucketName,
  Key: fileName,
  Fields: {
    "content-type": "image/png",
    "x-amz-meta-help": "No",
    "content-disposition": "attachment",
    acl: "public-read",
  },
});

And after I upload an image using the generated url and check the uploaded image in the Digitalocean spaces I can see that it correctly added the Content-Type and x-amz-meta-help metadata fields but not the Content-Disposition.

Is there any way to set content-disposition metadata without manually changing it through the ui?

Thanks,

Austin
