Helpdesk added to ERPNext failed

[sbsroc]

I had a hard time trying to get erpnext installed, but I managed to get it running this morning, added a few customers, suppliers, looked at the chart of accounts, etc. I decided to try installing the helpdesk module into the same site.

First, to install ERPNext, I did this:

docker compose --project-name erpnext --env-file /opt/erpnext.env  -f compose.yaml   -f overrides/compose.mariadb.yaml   -f overrides/compose.redis.yaml   -f overrides/compose.noproxy.yaml   config > /opt/erpnext.yaml
docker compose --project-name erpnext --env-file /opt/erpnext.env -f /opt/erpnext.yaml up -d

That's the abridged version for sure, since it was up, down, adjust file, up, down again... I also didn't have the project name in it at first, so the volumes and network were named differently, but I manually renamed the volumes and successfully started it up.

I then used this documentation to install helpdesk: https://docs.frappe.io/helpdesk/installation

I received an error about telephony not being included when I tried to install it:

builtins.ModuleNotFoundError: No module named 'telephony'

So, I re-ran get-app with --resolve-deps:

55d476201d4a:~/frappe-bench$ bench get-app helpdesk --branch main --resolve-deps
Following apps will be installed

1. telephony (required by helpdesk)
2. helpdesk
   Getting telephony
   ...

I finally ran the installation with:

frappe@55d476201d4a:~/frappe-bench/apps$ bench --site erp.example.com install-app helpdesk

and it seemed to work... but when I reloaded the web interface, I saw a 500 Internal Server Error. The backend log showed:

ModuleNotFoundError: No module named 'telephony'
 
During handling of the above exception, another exception occurred:
 
Traceback (most recent call last):
  File "/home/frappe/frappe-bench/apps/frappe/frappe/app.py", line 133, in application
    response = get_response()

During handling of the above exception, another exception occurred:

I tried to remove the application (module??) and install it again, but... it says it's not installed!

What am I doing wrong? I'm vary unfamiliar with frappe, bench, etc so it could easily be my misunderstanding... but I find the documentation to be very confusing.

Thank you!
