Breaking change on older node versions

[peshrawahmed]

🐛 Bug Report

I am currently using nodejs v9.5 and getting error on new client version v7.7.0 that has been released hours ago. I don't know if it is done intentionally or not(Sorry if it is done intentionally). But seems like older node versions does not work with the following declaration of generator functions:

async * FunctionName(){}

giving me error on lib/Helpers.js on line 56:

  async * scrollSearch (params, options = {}) {
        ^

To Reproduce

Running on an older version on node reproduces the error.

Hello! You are right, the recently introduced Helpers require a special flag for Node v8.
Unfortunately, even if you are not using them, this will break your code.

I'm working on a fix for the issue.

I've just released v7.7.1 on npm with the fix, thank you for reporting!
I would also strongly recommend migrating to a supported version of Node.js, as using an unsupported version could expose you to severe security risks.
You can find the officially supported versions of Node.js here.

Hello! Plase take a look at out Node.js support table, both Node v8 and v10 are no longer supported.

May sound silly but can you remove node_modules and package-lock files and run npm i again.

and also can you run node -v to double check if you are using the right version.
