Awkward behavior on error with pipe #640

Closed

Description

single exit 1 process - throws error

exit 1 process with piped - does not throw error

Is it intended behavior?

async function checkPipe() {
  try {
    await $`exit 1`.pipe($`echo hello`);
    console.log("not error at first");
  } catch (e) {
    console.log("it does not reach here (1)");
  }

  try {
    await $`exit 1`;
    console.log("it does not reach here (2)");
  } catch (e) {
    console.log("error catched!");
  }
}

await checkPipe();

Expected Stdout

$ exit 1
$ echo hello
hello
it does not reach here (1)
error catched!

Actual Behavior

$ exit 1
$ echo hello
hello
not error at first
file:///wd/temp.ts:106
    await $`exit 1`.pipe($`echo hello`);
           ^
