@tothstevee Have you confirmed what version of node your build is running?
Your build log will show it.

Hi! Yes i’m using v18.14.2

12:47:54 PM: Now using node v18.14.2 (npm v9.5.0)

@tothstevee Sorry I just realised you’re talking about functions not your build.

The version of node that your build is running has nothing to do with the version of node that your functions execute with.

See here for setting the node version for functions:
