mb they have a breaking change and we need to revert the library back or just fix the export path or function name?

[pedro-valentim]

hmmm, i was able to reproduce the error locally when using node v20.18.1 (v20 latest) and it seems to be resolved now

we can try again

[di-sukharev]

this wont be hit

[di-sukharev]

we need to remove the try/catch from the engines and prob do one try/catch in the Engine
