QUESTION
I'm experimenting with Node.js in AWS Lambda. And, I've run into a problem with the code below. Result value and error value are always returned blank. I'm pretty sure this is just a scope issue I'm to tired to see. How do I capture the return value and pass it back in the response? I'm sure the programs is connecting to redis because I get an error message if I change the port or URL and I don't when they're set properly.
The return code:
...ANSWER
Answered 2022-Apr-01 at 08:10It is because your call to "redis.get" is not resolved when "response" is sent.
You need to wait for the response :

I'm creating an API using NestJS and was trying to set up a session store for my express session but I get an error from this line. I did use express-session with Redis on a new project I created just using express beforehand to understand how Redis and express sessions worked but when I tried porting it over to NestJS it didn't work.
Main.ts
...ANSWER
Answered 2021-Aug-24 at 18:17The error states it right there. connect_redis1.default is not a function. Instead, you should use import * as conectRedis from 'connect-redis'. I've got an example here which looks like this:
QUESTION
I have a Node.js Google cloud function which I now try to modularize into two js modules. It works fine locally on my machine but when trying to deploy to Google I get the following error:
ERROR: (gcloud.functions.deploy) OperationError: code=3, message=Build failed: npm ERR! @babel/cli not accessible from data-model
My main-function is using my data-model module via the following entry in package.json:
ANSWER
Answered 2022-Jan-11 at 15:37I finally managed to solve this, got a bit side-tracked by the babel/cli error message that CloudFunction threw.
The issue was that my data-model module was in another directory:
"data-model": "file:../../data-model",
I put it inside the main-function instead:
"data-model": "file:data-model",
and it works just fine to deploy to cloud functions.
Why it is so I have no clue but it is kind of documented in the Google Cloud Docs too:
The code for this local module should be stored somewhere other than the node_modules folder within your function's root directory.

Answered 2021-Dec-15 at 05:22Maybe you were just using the wrong attribute to get that information. Checking the documentation at the Terraform Registry Website we can use the
cluster_ip attribute as described at the spec documentation description.
So you should end up with something like:
