com.github.dockerjava.api.exception.DockerClientException: Could not build image

[cpfarherFinitestate]

Hello I'm tring to build and run an image from a docker file using java. For that I have this dependencies in maven:

docker-java 3.3.6
docker-java-api 3.3.6
docker-java-core 3.3.6

I'm using this code:

 URL resourceUrl =
                        UploadBinaryScanRecorder.class.getClassLoader().getResource("com/fs/docker/Dockerfile");

        // Docker client configuration
        DefaultDockerClientConfig config =
                DefaultDockerClientConfig.createDefaultConfigBuilder().build();
        DockerClient dockerClient = DockerClientBuilder.getInstance(config).build();

        BuildImageCmd buildImageCmd = dockerClient.buildImageCmd();

        // Step 2: Set the Dockerfile
        buildImageCmd.withDockerfile(new File(resourceUrl.getFile()));

        // Step 3: Execute the build and get the result callback
        BuildImageResultCallback resultCallback = new BuildImageResultCallback() {
            @Override
            public void onNext(com.github.dockerjava.api.model.BuildResponseItem item) {
                // Handle build response
                System.out.println(item.getStream());
            }
        };

        buildImageCmd.exec(resultCallback);

        // Step 4: Await the image ID
        String imageId = resultCallback.awaitImageId(); // line 215

The exception was trigger in the line 215: String imageId = resultCallback.awaitImageId();

I confirmed that the image was build successfully:

Step 1/2 : FROM python:3.9-alpine
 ---> 8f4429cefc37

Step 2/2 : ENTRYPOINT [ "python3","--version"]
 ---> Using cache
 ---> a6b29bfb7257
null
Successfully built a6b29bfb7257

But I got this error and I don't understand why:

ERROR: Build step failed with exception

I need to get the imageId in order to run it later.

Thanks!
