When running local Debug on my function app the triggers will run and execute successfully, but they don't run the associated script file. A colleagues function app on the other hand will run the associated scriptfile on my machine when debugging locally.
Terminal output from run:

my function trigger:
{
"scriptFile": "__init__.py",
"bindings": [
{
"name": "myFunction",
"type": "timerTrigger",
"direction": "in",
"schedule": "0 */5 * * * *"
}
]
}
init.py in the function folder is never run for my triggers, but is on the same machine for my colleagues triggers. I've compared everything I can think of between our work and I just can't find any differences in how our triggers are configured or organized.
I have a virtual environment configured and activated and CLI is up to date.
I'm sure this is something I'm doing/have done wrong, but I can't figure out what that is.

__init__.pyfile. If possible can you please paste a snippet about how your main(myFunction) is defined in__init__.py? -

2020-09-03T06:14:09.14+00:00 After imports all of my functions
__init__.pyfiles start with:def main(myFunction: func.TimerRequest) -> None: utc_timestamp = datetime.utcnow().isoformat()Followed by subsequent loops.
Two of the tree functions in my app are already live and running in dev portal, and execute just fine. They run through the scriptfile and return all the logging statements therein. It's only on my local machine that I'm having this issue, and then only with this application and its triggers. So I assume it's something wrong with how I've set up something locally.
Edit: I added a complete terminal output from my local machine for the two functions that work on dev portal to my original post.

if colleague's Function app runs the associated script file locally try the following:- use yours
__init__.pywith colleague's Function app - if it will be called then problem is in Function app project itself. In this case you may also create new Azure function app project in VS and use your__init__.pythere. If it will work - just move other functions there and continue development on this new project - use colleague's
__init__.pywith yours Function app - if it will be called then problem is in__init__.pyfile itself. There may be some hidden unicode characters, or lack of whitespaces which may be crucial for running Python files

2020-09-03T18:16:20.567+00:00 Importing one of my
__init__.pyfiles into one of my colleagues triggers results in the same behavior. The Trigger will execute, but does not execute the associated scriptfile. I ran this in tandem with one of their existing unmodified triggers, which did execute correctly.Importing my colleagues
__init__.pyfile into my trigger exhibit the correct behavior. The scriptfile runs and all of its associated log statements show up in the terminal.I'll keep digging into my
__init__.pyand see if I can figure out what the difference is. But a cursory examination hasn't show anything notable.
