Response is not sent to S3, no error is thrown

[harshil-darji]

I have created an application wherein a lambda is inheriting the AbstractCustomResourceHandler class. It performs certain function on create/update events. I am also generating a presignedUrl and sending it as the ResponseUrl parameter for the CloudFormationCustomResourceEvent.

However, no output is produced in S3 bucket. For the permissions, I have setup s3 Full access and given it to the lambda function. I also tried overriding the onSendFailure function to perform any logging, but no log output is produced, implying that no error is thrown. Is there any additional S3 configuration I might be missing for this setup to work? Please let me know. Thanks.
