Unexpected Token while parsing file (spread operator)

[Gage Langdon]

I have tried to disable minification as i read as a solution from another issues here, but it still didnt work.

Unexpected token (273:46) while parsing file at Parser.pp$5.raise

[Daniele Pelagatti]

confirming this , on a snipplet like this

    const Item = {
      id,
      _contentType: contentModel.id,
      _createdAt: new Date().toISOString(),
      _modifiedAt: new Date().toISOString(),
      ...args.input
    }

I get this error

SyntaxError: D:/Users/x/Desktop/proj/serverless/lambda-functions/content/index.js: Unexpected token (264:6) while parsing file: D:\Users\x\Desktop\proj\serverless\lambda-functions\content\index.js

This is likely an issue with bowserify, no? See browserify/browserify#1802

[Gonçalo Neves]

Yes, Browserify doesn't support all new fancy syntax/statements. Please refer to Browserify docs.

For the sake of curiosity, what babel preset were you using?
