Hi @VincentSurelle - thanks for reaching out.
I'm not sure what your workflow looks like but if you're not using TLA (Top Level Await) in your application, you can consider moving API call inside the handler, although not recommended. If you could share your workflow and repro code, I'd be happy to further look into it.
Hello !
I don't think I can give more details with a repro than the code I show in the first message :
// ...
const client = new SSM();
// Here we are outside the handler -> During the cold start
// We start a promise -> Don't need to await it there since I won't need it now and don't want to extend cold start duration
// This way, promise is fired up, if cold start take, for example, 200ms after this line, that's 200ms earned on the request duration
const secret = client.getSecretValue(params);
const handler = async (event) => {
// Here i do some unrelated stuff that can take some time or no. Just unrelated stuff
doSomething();
doSomethingElse():
// Here, I need my secret.
// Promise was started during cold start. Maybe 10ms before. Maybe 100 or event 1000ms or 10 minutes ? Whatever
// But since I await my promise here. I have way more chances that it has been resolved.
// That some precious ms
doSomethingWithMySecret(await secret); // But if it's more than somes minutes after promise startup. The exception occurs
}
Now the problem appear with SDK V3
If it was a simple request like axios.get('https://amazon.com')
. No trouble
SDK V2 was ok with this.
SDK V3 is not
