Hi Guys, I am trying to store files to S3 by creating a module, by following SDK example [ignition-sdk-examples/scripting-function at master ยท inductiveautomation/ignition-sdk-examples ยท GitHub](https://github.com/inductiveautomation/ignition-sdk-examples/tree/master/scripting-function) I can use all scripts in designer. It shows error below: `software.amazon.awssdk.core.exception.SdkClientException: Unable to load an HTTP implementation from any provider in the chain. You must declare a dependency on an appropriate HTTP implementation or pass in an SdkHttpClient explicitly to the client builder.` How can I work with S3 properly?

Hmm, it's issue of AWS. ```auto S3Client s3Client = S3Client.builder().region(Region.CA_CENTRAL_1) .credentialsProvider(StaticCredentialsProvider.create(AwsSessionCredentials.create(ACCESS_KEY, SECRET_KEY, ""))) .httpClient(UrlConnectionHttpClient.builder().build()) .build(); ``` ---

Why following code is working on script console but not script panel when we bind to text? `import software.amazon.awssdk.regions.Region as Region;` ---

In the gateway, modules are installed into isolated classloaders--the contents are not exposed to the gateway as a whole. It works in the designer script console "by accident" because the designer (and vision clients) does not use more than one classloader. To expose classes in the gateway, you must initialize script functions in script managers using the proper gateway hook. ---

Got it! It made things more tougher. ๐Ÿ˜‚ ---

You can short-cut the process by exposing classes in fields instead of writing wrapper functions. In the class you register with the script manager, have lines like this: ```auto public static final Class AwsBasicCredentials = AwsBasicCredentials.class; public static final Class AwsCredentials = AwsCredentials.class; public static final Class S3Client = S3Client.class; public static final Class ListBucketsResponse = ListBucketsResponse.class; ``` If you register that as `system.amazon`, then your jython scripts can do this: ```auto from system.amazon import AwsBasicCredentials, AwsCredentials, S3Client, ListBucketsResponse ``` ๐Ÿ˜
