Cannot find module './stores/memory.js'

[Goufix]

I'm trying to change from a server aplication to a serverless one based on my needs. I've made all the steps to make it work. Based mainly on that tutorial.

When I run the aplication locally using sls offline start, it runs and works perfectly.

The real problem comes when I try to deploy it. The deploy comes successfully, but when I call any application route, it turns an 502 - Bad gateway / internal server errror. Trying to see the logs, there's an error called: Cannot find module './stores/memory.js'. And there's no stacktrace too.

serverless.yml

service:
  name: snackin-integrator

package:
  exclude:
    - './**'
    - '!node_modules/**'
    - '!dist/**'
    - '.git/**'

plugins:
  - 'serverless-plugin-typescript'
  - serverless-plugin-optimize
  - serverless-offline
  - serverless-dotenv-plugin

provider:
  name: aws
  runtime: nodejs14.x

functions:
  main: # The name of the lambda function
    # The module 'handler' is exported in the file 'src/lambda'
    handler: src/lambda.handler
    events:
      - http:
          method: any
          path: /{any+}

sls logs -f main output

Hello @Goufix, this tracker is intended for bugs and enhancement proposals, I will move this to Discussions.

As for your issue, this will end up excluding all files in your service directory:

package:
  exclude:
    - './**'

I believe this is not what you intended - which files do you want to exclude?

[Goufix]

I think none of them. But it is part of a lot of attempts to make it work. I think I can remove everything that I've put on the "exclude" key

[pgrzesik]

You might also want to try serverless-webpack plugin instead of the serverless-plugin-typescript and serverless-plugin-optimize as they're outdated

[Goufix]

Removing serverless-plugin-optimize worked for me. Thanks.
