I added caching: false and it's gone now

[PenguinOfWar]

Thanks @softmarshmallow for advising of the fix. Can I recommend you close this issue?

[jschuur]

I just ran into the same issue, and was able to fix it with caching: false, but shouldn't this plugin work out of the box without having to add a custom setting?

Disabling caching doesn't seem like something I want to do.

I switched from serverless-webpack to serverless-bundle, is it somehow conflicting with old cache content? I couldn't find any legacy cache directory in my project.

[jschuur]

I got it working without needing caching: false once I realised that I still had a newer webpack installed locally from when i used serverless-webpack. Once I removed that, it was all good.

[PenguinOfWar]

Thanks @jschuur for the additional information.

Pinging @jayair to close.
