@munishchouhan can you provide a sample code I can use to repro the error?
Are you using service-specific endpoint overrides?

[munishchouhan]

this is the code i am using

    S3Presigner s3presigner() {
        final builder = S3Presigner.builder()
                .region(Region.of(blobConfig.storageRegion))
                .credentialsProvider(DefaultCredentialsProvider.create())
        if ( blobConfig.storageEndpoint ) {
            builder.endpointOverride(URI.create(blobConfig.storageEndpoint))
        }
        return builder.build()
    }

you can find the class here:

can it be a dependency issue?

I am adding these three in my project, do i need to add some extra?

implementation "software.amazon.awssdk:ecr:2.28.15"
    implementation "software.amazon.awssdk:ecrpublic:2.28.15"
    implementation 'software.amazon.awssdk:ses:2.28.15'

[munishchouhan]

This turn out to be a missing dependency issue, when i dont mentioned any version, then i thnk micornaut provides teh whole sdk, but with version, i need to provide the depdency
adding this solves the issue
implementation 'software.amazon.awssdk:aws-sdk-java:2.28.17'

[munishchouhan]

but the whole sdk is too big, how to know which part is missing?

[debora-ito]

You need to add as a dependency the SDK modules that correspond to the service clients you want to use, plus any HTTP client if you want to customize its configurations - Apache and NettyNio are added automatically.

S3Presigner is in software.amazon.awssdk:s3, looks like s3 is missing from your list.

Another thing you can check is for version mismatches between SDK modules. Ideally all modules should be in the same version.

[munishchouhan]

thank you
s3 fixed the error
