[Error]: Breaking change introduced in ver. 9.3.6 (TypeError: split called on null or undefined)

[maverox]

@SBoudrias,

Breaking change introduced in this commit ec78662#diff-b24d4a707495e5e2f210d200fab3550db18877ded7d01e729bb73e0c9b103c55

I am using node-plop in my project and after this commit I believe I am getting an error on running only the prompts.

I think this is a breaking change

Please look at this issue for more context: plopjs/plop#445

[SBoudrias]

name is required for each prompt, do you know why/where is plop passing one with undefined?

That'd help me understand if it's an issue fixing within Inquirer, or if it's a bug plop needs to fix.

[maverox]

Okay so I was digging into node-plop and it's working and found out that it's only happening when I was using bypassPrompts functionality of runPrompts
but runPrompts method without it is simpling running inquirer which was running fine.

I believe the issue is at node-plop's end.

I would like your remark as to whether this is enough to consider this issue resolved and close this issue .

[SBoudrias]

Well I'd like to know someone fixes this on plop side. Seems like it confuses many of their users.

I can push a hotfix to the 9.x release branch.

[SBoudrias]

inquirer@9.3.7 includes a fix - but v10 over won't, so plop will need to fix this internally; or explain how that usage is expected (in which case I'm open to review this change.)
