Getting errors in SQS after updating mirth connect version to v4.5

[GregoryChung]

Hi all, I am getting error afters i upgraded my mirth connect from v3.1.2 to v4.5. We are currently using a custom jar file which we retrieved from our v3.1.2 version and placed it in the custom-lib folder, because the current jar file is created by our previous developer which left the team. We also tried to create the jar file ourself upon googling, but we still getting this "could not initialize class" but for different classes. Appreciate if anyone could provide some advice on this, as I am quite new into mirth connect.
Thanks!

SQS CODE:
`logger.info("LabResultInsertedId:"+JSON.stringify(parseInt(channelMap.get("LabResultInsertedId"))))
var software = Packages.software;
var sqsRegion = software.amazon.awssdk.regions.Region.AP_SOUTHEAST_1;
var sqsUrl = globalMap.get('LAB_RESULT_SEND_SQS_URL_DESTINATION');
var roleRequest = software.amazon.awssdk.services.sts.model.AssumeRoleRequest;
var StsClient = software.amazon.awssdk.services.sts.StsClient;
var roleArn = globalMap.get('LAB_RESULT_SEND_SQS_IAM_ROLE');
var roleSessionName = 'awssdk';
var stsBuilder = StsClient.builder().region(sqsRegion).build();

var roleRequest = roleRequest.builder().roleArn(roleArn).roleSessionName(roleSessionName).build();
var assumeRole = stsBuilder.assumeRole(roleRequest);
var sqsKey = assumeRole.credentials().accessKeyId();
var sqsSecret = assumeRole.credentials().secretAccessKey();
var sqsSessionToken = assumeRole.credentials().sessionToken();
logger.info(JSON.stringify(parseInt(channelMap.get("LabResultInsertedId"))))

var credentialsProvider = software.amazon.awssdk.auth.credentials.StaticCredentialsProvider.create(software.amazon.awssdk.auth.credentials.AwsSessionCredentials.create(sqsKey,sqsSecret,sqsSessionToken));
var sqs = software.amazon.awssdk.services.sqs.SqsClient.builder().credentialsProvider(credentialsProvider).region(sqsRegion).build();
var sendMessageRequest = software.amazon.awssdk.services.sqs.model.SendMessageRequest;
var r = sqs.sendMessage(sendMessageRequest.builder().queueUrl(sqsUrl).messageBody(JSON.stringify(parseInt(channelMap.get("LabResultInsertedId")))).build());
logger.info("Send To SQS Queue Channel: Sent Message to SQS.");`

JavaScript Writer java.lang.NoClassDefFoundError: Could not initialize class software.amazon.awssdk.services.sts.DefaultStsClientBuilder

Did you also load the AWS SDK JARs that include this class? Mirth includes some AWS libraries to support S3 but I do not know if they inlcude the STS classes.

Are you using custom-lib (the old way of loading custom code) or Resource Directories? This link explains why Resource Dirs are better.

Did you update your channel dependencies in the summary tab?

because the current jar file is created by our previous developer which left the team

If you're stuck or on a tight deadline, getting consulting hours could be helpful https://github.com/rogin/mirth-consulting

You can also do a few things to see whats in the JAR:

1. Unzip the JAR - the JAR format is just a ZIP archive of Java class files
2. Open the unzipped directory in a good IDE, I like IntelliJ and the community edition will be fine for this need
3. In the IDE, open the .class files. Most modern IDEs will automatically decompile the classes and let you see the source code.
