Exceptions when importing functions

[yannerous]

When importing functions from a file an exception is sometimes produced by the handle_write_package function without any clear pattern. They all produce the error message:

Traceback (most recent call last):
  File "protocol/ujsonrpc.py", line 1, in _handle_message
  File "commands/program_methods.py", line 1, in handle_write_package
Exception:

If you need more information from me, don't hesitate to ask.

My main file:

# LEGO type:advanced slot:0 autostart

from spike import PrimeHub
from spike.control import wait_for_seconds
from runtime.virtualmachine import VirtualMachine # Needed for newer hub versions (3.1.43+)
from test12 import *


async def on_start(vm, stack):
    hub = PrimeHub()
    print("Startup")

    vm.stop()


def setup(rpc, system, stop):
    vm = VirtualMachine(rpc, system, stop, "something_unique")
    vm.register_on_start("another_unique_string", on_start)
    return vm

Examples of files that could not be imported:

Example 1:

def test():
    return

def test2():
    return

Example 2:

def test():
    #test
    return

Example 3:

#test

def test():
    return

Examples of files that can be uploaded to the spike prime:

Example 1:

def test():
    return

Example 2:

#test
def test():
    return

After further testing, I found that the errors disappear for all examples if I remove the unused import wait_for_seconds or use it in the file:

# LEGO type:advanced slot:0 autostart

from spike import PrimeHub
from spike.control import wait_for_seconds
from runtime.virtualmachine import VirtualMachine # Needed for newer hub versions (3.1.43+)
from test12 import *


async def on_start(vm, stack):
    hub = PrimeHub()
    print("Startup")
    
    #use the imported function in the file
    wait_for_seconds(1)

    vm.stop()


def setup(rpc, system, stop):
    vm = VirtualMachine(rpc, system, stop, "something_unique")
    vm.register_on_start("another_unique_string", on_start)
    return vm

I will keep this issue open, in case someone else experiences similar problems or if there is an easy fix available.
