There is some kind of error that is occurring when trying to run a lambda function using the invoke command from the javascript SDK. Not sure if I'm doing anything wrong. please advise. This works with a live lambda function.

Call from AWS SDK (Javascript)
```
const { source, identifier } = ctx.params;

const bodyBuffer = await requestToBuffer(ctx.request.req);
const bodyBase64 = bodyBuffer.toString('base64');

const payload = {
        pathParameters: {
            source,
            identifier,
        },
        isBase64Encoded: true,
        body: bodyBase64,
    };
const response = await lambda.invoke({
        FunctionName: 'arn:aws:lambda:us-east-1:000000000000:function:uploadAvatar',
        InvocationType: 'RequestResponse',
        Payload: JSON.stringify(payload),
    }).promise();
```

**Note**: I also tried just using uploadAvatar for the function name.
