What is the "Pulumi native" way to handle getParameter when one does not exist? I can handle it with the SDK:

const ssmClient = new aws.sdk.SSM();
ssmClient.getParameter({ Name: "does-not-exist" }, function (err: any, data: any) {
  if (err) {
    new aws.ssm.Parameter("foo", {
      type: "String",
      value: "bar",
    });
  }
});

but it errors when I try to handle one not existing with getParameter:

pulumi.output(
    aws.ssm.getParameter({
      name: "does-not-exist",
    }),
  ) ||
  new aws.ssm.Parameter("foo", {
    type: "String",
    value: "bar",
  });

Error: invocation of aws:ssm/getParameter:getParameter returned an error: invoking aws:ssm/getParameter:getParameter: 1 error occurred:
        * Error describing SSM parameter (doesn-not-exist): ParameterNotFound:

You might be able to use getParametersByPath with a very specific path: https://www.pulumi.com/registry/packages/aws/api-docs/ssm/getparametersbypath/

Seems like not the Pulumi way? As a rule, if you ever intend to manage the Parameter, then you should always manage the parameter.

That's a good point, I'll ask more about the requirements.
