Aws-lambda-dotnet: Amazon.Lambda.TestTool 0.10.1 is not working but 0.9.5 is

[matsola]

Hi,

We have experienced a problem when upgrading from 0.9.5 to 0.10.1 for Amazon.Lambda.TestTool.

We are working in Rider and when we try to start we get a couple of different error messages.

A fatal error was encountered. The library 'libhostpolicy.dylib' required to execute the application was not found in '/Users/.../.dotnet/tools/.store/amazon.lambda.testtool-2.1/0.10.1/amazon.lambda.testtool-2.1/0.10.1/tools/netcoreapp2.1/any/'

And when trying to debug: dgbshim directory missing. But this might be releated to Rider.

Has anyone any idea why this might be happening?

If i add the file Amazon.Lambda.TestTool.runtimeconfig.json to /Users/.../.dotnet/tools/.store/amazon.lambda.testtool-2.1/0.10.1/amazon.lambda.testtool-2.1/0.10.1/tools/netcoreapp2.1/any/ I get a bit further and actually is able to run the application but dotnet crashes.

❯ dotnet --version
3.1.201

❯ dotnet --list-sdks

Thanks for letting me know. The documentation on the README file was out of date which has now been updated.

As part of the 0.10.0 the tool was broken up to support both .NET Core 3.1 and 2.1. In the old version Amazon.Lambda.TestTool.dll was the entry point assembly but now that is just a class library. There is a separate entry assembly for either .NET Core 3.1 or 2.1 called Amazon.Lambda.TestTool.WebTesterXX.dll.

Check out the updated README file and let me know if that clears things up.

Thanks for the update.

Now it seems to be working!

Thanks!
