error when deploying a lambda suddenly [golang CDK]

[davemackintosh]

This has worked for months and months fine for me but it suddenly stopped working recently with this error. panic: The "list[2]" argument must be an instance of Buffer or Uint8Array. Received type string ('bootstrap').

This issue only affects one of my functions which is a Cognito hook. I'm using, I tried rolling back but it didn't fix it. It doesn't happen 100% of the time but maybe 90% of the time so I'm at a loss.
