node ES6 import throws this error. #61

The only thing I can think here is that your target Node.js environment is somehow running an incredibly low memory environment that cannot allocate / execute a normal sized Wasm binary. Where are you running Node.js in this case? We could better support the ability to fall back to the JS implementation possibly but this is the first time we've heard of any Wasm execution issues in core so there must be some very specific environment contraints you are running under? |

I am running this in my cpanel. |
Which cpanel are you using here? |
|
I am using the cPanel provider babal.host, there is the plan called node js starter plan. here is the screenshot, |

I have the same issue, using cpanel from fullhost.io. |

@KevinBrogan thanks for reporting. Could you perhaps share the output of |
|
debug.js command line (import works) output debug.php command line (import works) output website url in browser (import causes crash) output |

@KevinBrogan thanks for the info, but this still doesn't really narrow it down unfortunately. Do you know how is PHP calling into Node.js here? Is this a long-running JS process or is it being instantiated on each PHP request? Any information you have to help us dig into this further would be great. |

I know that php is using the back tick operator to call node via a
shell_exec, but I couldn't tell you much more than that. It's not a
long running process. It is instantiated on each request.
php command line works, it's only php via the server that is not working.
The http server is LiteSpeed
I also know that when I use my personal Apache server, everything works fine. It's
only on the hosted server that this issue comes up.
Server php API is LiteSpeed V7.9 Cloudlinux 1.3
php is 7.3.29

@KevinBrogan is there any way you can check the output value of running the command |

ulimit is set to unlimited from the command line, but 2GB when executed
from the server. Increasing to 4GB, which is how much memory the machine I
got it to work on has installed, made no difference.
Essentially, if I'm understanding this correctly... The webassembly is
allocating more memory than there exists on the system, with no intention
of using it all.
The web assembly needs a large unbounded virtual address space, for
whatever reason, so any ulimit on the virtual address space will cause the
program to crash.

I have the same issue by setting ulimit. I noticed there were no problems in other versions but the error comes in starting in |

Bump: I am also facing this issue, can easily reproduce by setting ulimit, and just imporint a single CJS module (in my case dotenv). Made an issue on node as well -> nodejs/node#42222 |

I've posted a possible fix in nodejs/node#43612. |
