Are there cases where "e" is not an Error? I have not encountered them but interested to hear if you've seen this!

I think this is the original proposal. It tries to be more specific on the error types, like other languages. Like the example from that thread

try {
  externalApi()
} catch(e) {
  if (e instanceof Error) {
    // Probably send this error to developer of API
  } else if (e instanceof ApiError) {
    // We messed up, log it and fix it in next patch
  }
}

message.destroy();
message.error({ content: `Update Failed! \n ${e.message || ''}`, duration: 2 });
if (e instanceof Error) message.error({ content: `Update Failed! \n ${e.message || ''}`, duration: 2 });
}
onCloseModal();
};
