The request signature not match.

[geetoor-maven]

I get this error when i put Object to s3 bucket : " The request signature we calculated does not match the signature you provided. Check your AWS Secret Access Key and signing method. " and strangely when I took the bucket, I definitely didn't get an error like signature not match ( everything went smoothly ).

And I have made sure all the secret keys from s3 are correct.

i use this version dependency :

<dependency>
	<groupId>software.amazon.awssdk</groupId>
	<artifactId>s3</artifactId>
	<version>2.30.0</version>
</dependency>

and i use the java version 17 and spring boot 3.4.1.

is this a bug or just a version error?

Are you sending the request to a third-party AWS-compatible solution or to S3 directly?
Can you share a repro example?

[geetoor-maven]

yes i sending the request to a third-party AWS-compatible.

this is repro example :

PutObjectRequest putRequest = PutObjectRequest.builder()
                .bucket(bucketName)
                .key(keyName)
                .contentType("text/plain") 
                .build();

s3Client.putObject(putRequest, RequestBody.fromFile(Paths.get(filePath)));

@Bean
    public S3Client s3Client(){
        return S3Client.builder()
                .serviceConfiguration(s3Config)
                .endpointOverride(URI.create("endpoin url third party"))
                .credentialsProvider(StaticCredentialsProvider.create(
                        AwsBasicCredentials.create("access key", "secret-key")
                ))
                .region(Region.of("my region"))
                .build();
    }

Right, so the third-party solution is most likely impacted by a change released in the Java SDK version 2.30.0 announced here. The third-party needs to accommodate the changes on their side, you should reach out to their support team.
