Does Api Gateway allow post request without request body

Question

I have created and enpoint that has path param as id and using that it fetches data from db and then posts the data from database using http. I am using AWS ApiGateway to manage this endpoint however, when I pass the id and try to test the endpoint on api gateway without request body or some random valid request body, it shows:

"errors": [
        {
          "title": "Error in API Gateway",
          "code": "DEFAULT_5XX"
        }
      ]

It also shows the following in the logs:

Illegal character in path at index 101: http://example.local/orders/items/create/{id}

Answer 1

To answer your question, yes, we can do a POST on API Gateway without a body. The error is pretty clear, it is an illegal character in the path.

There is a post on AWS FAQ about this. The solution is to add a proxy path variable in the integration request pane such that it does not run any validation checking on this particular path of the path.
