It used to work by doing Object.keys(api_variable.functions) in version 0.30.0 but something seems to have changed with the api construct where now I can use api_variable.routes, but that just returns “GET /“. Which the documentation seems to allow me to use api_variable.getFunction(“GET /“), and I thought I was out of the woods but that returns a function object that when I try to grab the property it resolves to this opaque ${Token[TOKEN.1056]} that I can’t seem to turn into anything related to an actual functionArn that AWS will understand?

09/24/2021, 11:31 PMThe token you're getting is at build time. When that is sent to AWS they resolve the token to a real ARN (it doesn't exist at build time). You can pass that anywhere else in sst and it should work

09/24/2021, 11:31 PMcan you share more about what you need to do with the ARN?

09/24/2021, 11:32 PMThe way you have it is the right approach, using
api.getFunction("GET /")t

09/24/2021, 11:32 PMAh I see, it’s just odd because the 0.0.30 serverless actually resolved to a real functionArn during the execution of MyStack.js which successfully was passed to and used by functions later in the MyStack.js file
Tony J
09/24/2021, 11:33 PMExample of how I used it before: let api_function_arns = [];
let api_function_keys = Object.keys(api.functions);
for (let i = 0; i < api_function_keys.length; i++) {
api_function_arns.push(api.functions[api_function_keys[i]].functionArn);
}

09/24/2021, 11:34 PMThen I would pass to a function I wanted to have access to it like so:
Tony J
09/24/2021, 11:34 PMnew sst.Function(this, “function”, {
bundle: {
nodeModules: [“saslprep”],
},
handler: “src/utils.handler”,
timeout: 30,
environment: {
stage: scope.stage,
function_arns: JSON.stringify([
...api_function_arns
])
}
});

09/24/2021, 11:35 PMHave you tried that? I think it should work - I don't know exactly how AWS's token replacement works but it should theoretically support that

Tony J
09/24/2021, 11:35 PMYeah if I take the 0.0.30 code running in production and just upgrade it fails at build time because it cannot do Object.keys(api.functions) anymore
Tony J
09/24/2021, 11:35 PMOne sec I can run it right now and give a better answer

09/25/2021, 12:04 AMHaving it as tokens works fine I’m an idiot sorry
Tony J
09/25/2021, 12:04 AMFor some reason I remember getting actual Arns even while executing the MyStack.js but I guess not
