{"errorMessage": "Unable to unmarshal input: Expecting value: line 1 column 1 (char 0)", "errorType": "Runtime.UnmarshalError", "stackTrace": []}

Question

I followed this tutorial.

Steps:

I downloaded this github.

from where I installed the project, I executed this:

docker build -t logbert-lambda .
docker run -p 8080:8080 logbert-lambda

I opened my navigator and I typed: http://localhost:8080/2015-03-31/functions/function/invocations

It gave me this error: {"errorMessage": "Unable to unmarshal input: Expecting value: line 1 column 1 (char 0)", "errorType": "Runtime.UnmarshalError", "stackTrace": []}

Can't I use my navigator rather than Postman ?

Answer 1

The tutorial is clear about what HTTP method you have to use:

The endpoint functions/function/invocations handles requests of type POST and requires some url encoded data in the body:

If you use your browser, you are making a GET request and, of course, posting no data.
