LambdaInvokerFactory Unsupported Operation: Cannot evaluate
I am invoking an AWS Lambda function directly from my Android app. I have the Request class:
private class MyRequest
{
String param;
public SetIdentityRequest() {}
public SetIdentityRequest(String param) {this.param = param;}
public String getParam() { return param; }
public void setParam(String param) { this.param = param; }
}
I don't need any values returned, so I don't have a Response class. I tried making an empty one in case that was causing my problem, but I got a lot more errors.
My interface class:
private interface MyLambda
{
@LambdaFunction
void myLambda(MyRequest req);
}
And finally my code for calling it:
LambdaInvokerFactory factory = new LambdaInvokerFactory(getApplicationContext(), Regions.US_EAST_1, credentialsProvider);
MyLambda lambda = factory.build(MyLambda.class);
lambda.myLambda(new MyRequest(someString));
Now, the lambda does actually go through and execute properly, so this isn't a dealbreaking kind of error; but I've been seeing when I step through it in debug that the line that has factory.build gets an error Method threw 'java.lang.UnsupportedOperationException' exception. Cannot evaluate com.myapp.$Proxy1.toString(). What is this error about? Do I need to worry about it? What do I need to do to stop getting this error?

Hello! Can you confirm the code for constructing the factory object compiled? It should beRegions.US_EAST_1however you don't have the plurality (Regions). Can you post the complete stacktrace? What is the frequency of this exception?

Yes, it was a transcription error here in the question; it's Regions in the original code. I have updated the question. I don't have a stacktrace for where the error is actually occurring; the build method that is reporting the error still returns successfully, but the debugger tells me it threw an exception, but I don't have an exception object to analyze. This seems to be happening every time I slow down the debug to look at it.

You can get the stacktrace from Logcat. Without a stacktrace it is difficult to analyze the issue further.
