Hello everyone! We have a NextJS website deployed to AWS via sst, our java backend is completely separated from it. It’s the second time in a couple of weeks that we receive warnings from CloudWatch caused by the default NextSiteApiFunction lambda created on deployment by sst. The logs read as follow:

{
  "errorType": "Runtime.UserCodeSyntaxError",
  "errorMessage": "SyntaxError: Unexpected token 'export'",
  "stack": [
    "Runtime.UserCodeSyntaxError: SyntaxError: Unexpected token 'export'",
    "    at _loadUserApp (/var/runtime/UserFunction.js:98:13)",
    "    at Object.module.exports.load (/var/runtime/UserFunction.js:140:17)",
    "    at Object.<anonymous> (/var/runtime/index.js:43:30)",
    "    at Module._compile (internal/modules/cjs/loader.js:999:30)",
    "    at Object.Module._extensions..js (internal/modules/cjs/loader.js:1027:10)",
    "    at Module.load (internal/modules/cjs/loader.js:863:32)",
    "    at Function.Module._load (internal/modules/cjs/loader.js:708:14)",
    "    at Function.executeUserEntryPoint [as runMain] (internal/modules/run_main.js:60:12)",
    "    at internal/main/run_main_module.js:17:47"
  ]
}

This burst of errors is limited to a 15 min timespan, before & after the logs are are fine with no other issues reported. We’re not making any use of the

/api

routes in the NextJS project so we don’t need any support for its “backend”. Would you have any tip on how to troubleshoot this issue? Thank you in advance!

Hey @Michele sorry for the late follow up, I got it to reproduce on my end.

Hi @Frank I missed your ping, thanks for looking into it and solving the issue! To upgrade to v0.60.5 - and to upgrade sst in general - should I just change the

@serverless-stack-slack/cli

and

@serverless-stack/resources

version in the package.json file? I tried running

npm update @serverless-stack/cli @serverless-stack/resources

but this only updates the package-lock.json, the version for those packages stays at our current one (v0.53.2) in package.json. Apologies for the naive question, not too knowledgeable in this topic 😅

You can use the

sst update

command, ie.

npx sst update 0.60.5

. With the exception that if you are currently on a version earlier than

0.59.0

, you’d have to follow these steps to update to

0.59.0

first.

Really appreciate all the help given, thank you!
