Error encountered when operating on dynamic arguments

TwelveNights opened this issue · comments

I've noticed a problem with dynamic arguments when using edge-js to create a C# function in Javascript, specifically when operations are performed on the dynamic argument. Please take a look at the following test which illustrates this behaviour:

docker run --rm -it debian:bullseye-slim bash

# in the container
export DOTNET_CLI_TELEMETRY_OPTOUT=1
export DOTNET_ROOT=/opt/dotnet
export PATH="${PATH}:${DOTNET_ROOT}"
export DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=1

apt update && apt install -y wget curl git unzip python3 make g++

mkdir /opt/dotnet
cd /opt/dotnet
wget -nv https://download.visualstudio.microsoft.com/download/pr/1d2007d3-da35-48ad-80cc-a39cbc726908/1f3555baa8b14c3327bb4eaa570d7d07/dotnet-sdk-6.0.403-linux-x64.tar.gz
tar -xzf dotnet-sdk-6.0.403-linux-x64.tar.gz -C /opt/dotnet
rm dotnet-sdk-6.0.403-linux-x64.tar.gz

curl -fsSL https://deb.nodesource.com/setup_16.x | bash - &&\
apt-get install -y nodejs

cd /tmp

npm i edge-js
node -p 'require("edge-js").func(`(dynamic ctx) => { return "Hello, " + ctx.ToString(); } `)("World!", console.log);'

The result I receive is:

/tmp/node_modules/edge-js/lib/edge.js:177
    return edge.initializeClrFunc(options);
                ^

The line that stands out to me is CS0656: Missing compiler required member 'Microsoft.CSharp.RuntimeBinder.Binder.BinaryOperation'. I've tested this with the following functions and they all seem to work:

  • async (dynamic ctx) { return ctx; };
  • async (dynamic ctx) { return "Hello, " + "World!"; }

So it seems to be the fact that we're trying to operate between the dynamic type and the ordinary string value. Please let me know if there's a workaround for this behaviour, or if you'd like additional information.

Please take a look at https://github.com/agracio/edge-js-quick-start, dynamic inputs work correctly.
