2021-02-26 00:00:23 UTC - Mina Michael: Hey guys. I have a question that should
be very basic.
I have a very simple javascript file. It's meant to run in nodejs. It's
basically a function that does simple queries to a mongodb database.
Now, this function requires `mongodb` to run. Like this for example: `const {
MongoClient } = require("mongodb");`
Now, I'm trying to convert this js code into an openwhisk function. How do I
correctly require libraries? Because in the general setting, I need to do `npm
install --save mongodb`.

2021-02-26 01:53:46 UTC - Mina Michael: One more question. Does openwhisk
support "async await"? Can I make "main" an async? And then, will openwhisk
return what gets resolved?

2021-02-26 03:35:17 UTC - Mina Michael: I have created an `async function
main() { }` and created a function on openwhisk. However, when I tried to
invoke it, I got this error:
```{
"error": "Initialization has failed due to: Action entrypoint 'main' is not
a function."
}```
Is this because the function is async? Does that mean that async functions are
not supported?
Here is what I'm trying to do. I'm trying to create a function that does
mongodb queries, and returns a result that depends on those queries. Without
async support, how can I do it?

2021-02-26 04:06:00 UTC - Mina Michael: I've tried with a non async function.
Just one that returns a promise. I'm still getting the same error.
```{
"error": "Initialization has failed due to: Action entrypoint 'main' is not
a function."
}```
What can possibly be the cause of this? I thought it was related to async at
first. I've been searching. Is it a bug?

2021-02-26 04:07:44 UTC - Mina Michael: I have tried setting `--main
global.main` like they say here
<https://github.com/apache/openwhisk-runtime-nodejs/issues/138> but it didn't
work.

2021-02-26 04:43:35 UTC - Mina Michael: Okay. I have the same javascript
function (non async). I have given it to openwhisk once as a js file and once
inside a zip file. The first attempt (as a js file) worked completely fine. It
returned the result. But the second one (as a zip file) didn't work. It gave
the same error.
I named the file "index.js" as requested by openwhisk. What can I be possibly
doing wrong?
