Description

Unable to launch AWS SAM LOCAL on MAC with eclipse due to a NPE.

1. Create the Hello World App in Eclipse, with out any modification.
2. Follow the steps to install SAM Local
3. Re launched Eclipse
4. Right click on the java file and select "Run as" -> "AWS SAM Local"
5. waited for a bit and then I get a NPE.

Steps to reproduce

Provide steps to replicate.

Observed result

I noticed that I can correctly invoke the app by launching it from the SAM cmd line as such:

1. sam local start-lambda -t serverless.template
2. aws lambda invoke --function-name "HelloWorld" --endpoint-url "http://127.0.0.1:3001" --no-verify-ssl out.txt
3. Output is:

   {
       "StatusCode": 200
   }
   

Details of software:

1. OS: 10.14.5 (18F132)
2. sam --version: AM CLI, version 0.22.0
3. DOCKER-desktop: 2.1.0.3

How long will it take for someone to look into the issue? It took over a month for someone to look into the other issue. I know there is a lot of us out there.. just wondering if this is something simple or a complete bug, the fact that is a npe tell me is a bug... :)

Hi @arvera, thanks for reaching out.

The Eclipse toolkit currently does not support the latest version of the SAM CLI. 1 2

We've been asking users to try out the AWS Toolkit for JetBrains

We'll mark this as a bug, but are there any limitations (technical or otherwise) keeping you on Eclipse?

I am most familiar with the eclipse environment. I was an eclipse developer a few years back.. so.. is my natural habitat.

I am having the same issue - with the accompanying code in the console log:

In regards your question about JetBrains - the free edition is not sufficient for the work I do and the cost of the fully featured edition is prohibitive.

Any update on this issue? I don't think changing IDEs is an acceptable workaround.
