First App - Post request - error in saving

Serverless Framework

Hi

I just completed the How to create a REST API in Java using DynamoDB and Serverless tutorial.

I associated my aws account to serverless client via commandline
serverless config credentials --provider aws --key KEYKEYKEY2001--secret SECRETSECRET100001

All lambda functions are created, dynamoDB table, s3 bucket all created etc. I have fully ported in all code from the github example. The only change is the aws region from US to EU.

However, when I try and POST to create a demo product it fails to save. It connects correctly but fails to write to the DB

curl -vvv -X POST https://xxxxxxxxxxx.execute-api.eu-west-1.amazonaws.com/dev/products -d '{"name": "Product1", "price": 9.99}'

Note: Unnecessary use of -X or --request, POST is already inferred.
*   Trying 143.x.x.x...
* TCP_NODELAY set
* Connected to xxxxx.execute-api.eu-west-1.amazonaws.com (143.x.x.x) port 443 (#0)


"message": "Error in saving product:

It looks like there is a message from your Lambda. You should be able to see potentially more error detail in CloudWatch as that is where error messages go by default.

Hi @garethmcc

Thanks for the reply. Not much luck there. I can request coming in but it complains about no log4j appender despite it being in my dependencies

Are you explicitly logging the error message?

Regarding the log4j warning, do you have a log4j config file included in the deployment package?
