I'm trying to handle exceptions in typescript (inside of an async code). What would be the proper way of handling it? I've not found an exception class or something that I could use to cast such error.

error: Running program '/home/user/development/company/aws-iam-provisioning' failed with an unhandled exception:

Error: invocation of awsssm/getParametergetParameter returned an error: invoking awsssm/getParametergetParameter: 1 error occurred:

* Error describing SSM parameter (eks-name2): ParameterNotFound:

The code:

Copy code

try {
    const eksName = await aws.ssm.getParameter({
    name: "eks-name",
    });
} catch(error) {
    // handle error
    console.log(JSON.stringify(error));
}

inside of the catch block, the below will be printed:

Copy code
{
  "promise": {}
}

so it's like I don't have access to the error message, etc could be I'm just lacking some JS/TS skills as well, but I think it should be something like that

Copy code

const eksName = await aws.ssm.getParameter({
    name: "eks-name",
}).catch(err => console.log(err) /*handle here*/)

@steep-toddler-94095 even with the await there you still have to use the catch function? That's a bit counter intuitive, no? Could be I'm lacking some knowledge here as I'm not a nodejs expert

you're correct, you don't need the

await

for the

.catch

to work
