Serverless Stack

:boom: I’ve got a critical issue going on with 1.1.2. things were fine in 1.0 beta 7, but now one of my functions is throwing this error (see in thread)

`This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). The promise rejected with the reason:`
`TypeError: Cannot convert undefined or null to object`

pretty sure this is happening with the `import` of AWS AppSync

yep.
```import AWSAppSyncClient from 'aws-appsync';
...
console.log('y tho?', AWSAppSyncClient);```
:point_up: throws error

I don’t wanna assume this is just when working locally, so I’m really hesitant to push this to production

hey <@U01JVDKASAC> <@U01MV4U2EV9> - wanted to put this on your radar. obviously it’s a pretty severe edge case, as all of the other functions work just fine.

can you try a fake function where there's literally nothing but the import

yeah if I remove the `console.log` it’s fine. but.. tree-shaking I assume

which is why I had to just log it, so there was a reference to it and it wasn’t removed from the build

and anything without this import is fine?

yeah, most of my functions work fine. except the ones that depend on `AWSAppSyncClient`

that is really odd, idk what on our end changed besides an update to cdk

can you create a simple function file like this

```import AWSAppSyncClient from "aws-appsync"

export function handler() {
  console.log(AWSAppSyncClient)
}```
add it to your stack and send me what shows up in the `.sst/artifacts` folder

er.. well.. it’s gonna take a long time :confused: when going from 1.0 beta to 1.1, it updates every Lambda function and I have a _lot_

ok. whew. now lemme whip up that function

<@U01MV4U2EV9> ok, so what do you want to see? the file `.sst/artifacts/dev-microservices-api-misc-Lambda_GET_-abc/src/lambda/rest/functions/abc.js` is quite large

looking into this: <https://github.com/aws-amplify/amplify-js/issues/9591>

ok, downgrading to AppSync 4.0.0 works! strange that the latest version was ok in SST 1.0 beta but not 1.1.2

hmm.. was Function runtime changed when updating to 1.1.2? Nodejs 16 related by any chance?

<@U01JVDKASAC> no, I’m hard set at 14.x
