[madhubikkavolu1]

Describe the bug

When i upload the json file to S3 bucket using presign url. below data is getting added inside the file body of json file.

Below is the data getting added when uploaded from postman and Insomnia tools respectively

----------------------------877876629424195648035655 Content-Disposition: form-data; name="file"; filename="sourceFile.json" Content-Type: application/json.

--X-INSOMNIA-BOUNDARY Content-Disposition: form-data; name=""; filename="sourceFile.json" Content-Type: application/json

Java code for generating pre-sign url :

public static String generateAWSPresignedUrlForBulk(final String spaceId, final AmazonS3 s3Client, final long timeToLive, final String bucket,
final String uuid, final String fileName, final HttpMethod httpMethod, String profile) {
Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider());
final var expiration = getExpirationTime(timeToLive);
final var generatePreSignedUrlRequest = new GeneratePresignedUrlRequest(bucket, buildKey(spaceId, uuid, fileName)).withMethod(httpMethod)
.withExpiration(expiration);
LOGGER.info(\"generateBulkPostDocumentPreSignUrl: \" + generatePreSignedUrlRequest);
LOGGER.info(\"S3 Key is: \" + buildKey(spaceId, uuid, fileName));
return s3Client.generatePresignedUrl(generatePreSignedUrlRequest).toString();
}

SDK version used : aws-java-sdk-s3:1.11.792

Hi @yasminetalby ,

We are uploading json file through postman tool using presign url which we generated using above java logic.

Hello @madhubikkavolu1 ,

Thank you very much for providing this screenshot. This does not seems related to AWS Java SDK behavior.

I have done some research and it seems that it is the behavior to except: when using postman with body->form-data, Postman is adding the header to your file.

If you would like to receive guidance regarding this behavior here are the repository where you can open submission tickets: postmanlabs/postman-app-support

If you have any questions related to the use of s3 presigned url or AWS-JAVA SDK V1 please let me know,

Sincerely
