aws java sdk for ssm gives java lang NoSuchFieldError SIGNING REGION

Question

Following code gives NoSuchFieldError when used in Lambda. The same works in a simple java program. Appreciate any help

AWSSimpleSystemsManagementAsync client = AWSSimpleSystemsManagementAsyncClientBuilder.defaultClient(); 

PutParameterRequest putRequest = new PutParameterRequest(); 

putRequest.setName("testKey");

putRequest.setValue("testValue");

client.putParameter(putRequest);

Digging into the source code shows error at AWSSimpleSystemsManagementClient.java -> request.addHandlerContext(HandlerContextKey.SIGNING_REGION, getSigningRegion());

Also tried with AWSSimpleSystemsManagementClientBuilder.standard(); AWSSimpleSystemsManagementClientBuilder.defaultClient();

WSSimpleSystemsManagementClientBuilder.standard().withRegion("us-east-1").build(); returning the same error

You may start with Checking that you have don't have a mistmach of aws versions. you might be having the same issue I had, upgrading ssm aws version to 1.11.301 while other components had the 1.11.271 aws core version, causing the same exception. You should make sure versions are aligned.
I know this is not much of a help but all you can do is this.
Give it a try and do let me know whether it worked or not.
