Yes this is an issue we're having too, it should be fixed as soon as we have some time to look into it.
Best,
Thanks for the feedback, I totally agree that this should of been provided by Amazon, but I'm hoping that eventually we can work with Amazon on this project.
It's funny because we just found this exact error ourselves this morning. For now, we're just using cloberring to make it work for now since we're on a tight deadline and can't fix this issue right away.
It would be greatly appreciated if you could take a whack at making it work. If not, I'll probably get to it this weekend.
Cheers!
Actually, this took precedent because we had things dependent on this to work. @tnbredillet was kind enough to provide a fix.
Hope this helps and please let us know of any other issues.
Cheers.
I've just tested with version 0.2.3. The problem persists.
I don't know if it could be related, but my code is invoking the mapper's save method for a non existing item. However from the stack trace I can see that Alternator client is invoking UpdateItem instead of PutItem.
KR,
Interesting. Thanks for the feedback, we'll look into it.
Thanks for your feedback, Actually if you use the normal mapper.save you have two saving behavior : -UPDATE ( by default if nothing is specified that is what your are using - that's an UpdateItemRequest) -CLOBBER (that's a PutItemRequest )
I just pushed version 0.2.4 this should be fixed. Let me know if it persists.
Hi,
First of all, thanks for your library. I think this should have been provided by Amazon since begining.
I've just started to use Alternator today. Previously I've been running my tests with an AWS account. The problem is that when I try to add a new item to a table, I get tle following exception: com.amazonaws.AmazonClientException: Unable to marshall request to JSON: null.
I'm using DynamoDB mapper and have my classes properly annotated
I don't know if this is a problem with my code or bug.
The stack trace is:
