Error while installing ERPNext app on bench in dockerized development set up AttributeError: 'NoneType' object has no attribute 'options'

Fellow community members,

Can you please help in resolving my issue?

My environment:
OS: Windows 10 Pro
Docker: Docker Desktop
Editor/IDE: Visual Studio Code-Insiders
I followed all the steps diligently from this link : frappe_docker/README.md at main · frappe/frappe_docker · GitHub.
I also referred to : Frappe_docker Getting started OSError: setuptools pip wheel failed with error code 1 - #3 by Osam
and Test images on Windows · Issue #137 · frappe/frappe_docker · GitHub

All the steps perfect until the last step of installing custom app. I tried Erpnext app : bench get-app erpnext GitHub - frappe/erpnext: Free and Open Source Enterprise Resource Planning (ERP) – Worked fine.
bench --site mysite.localhost install-app erpnext – This is where I got the errors.

frappe@d0badfa2ce18:/workspace/development/frappe-bench$ bench --site latsite.localhost install-app erpnext

Needless to say, I’m Frappe/ERPNext newbee

I checked tabDocField table, and I see some values. Also, see there is a column name “Options”.
On side note, can someone please suggest how to connect to mysql instance inside this container from mysql workbench? I tried, localhost and also tried to set host as % as root as well as new user. But, failed to connect from mysql work bench.

I’m not able to replicate this.

if bench is init without specifying --frappe-branch it installs frappe on develop branch. refer: bench init --help
if get-app doesn’t specify --branch it gets develop branch. refer bench get-app --help
both frappe and erpnext must be on branch with same name. e.g. version-12

edit .devcontainers/docker-compose.yml. you need to publish mariadb ports to host.
If on windows and using docker-machine, you will need to find out how to connect mysql workbench to docker machine instead of localhost

Thanks alot, @revant_one for your reply.

Your suggestion on how to connect from mysql workbench worked like a charm!

Blockquote edit .devcontainers/docker-compose.yml . you need to publish mariadb ports to host.
If on windows and using docker-machine, you will need to find out how to connect mysql workbench to docker machine instead of localhost

As you suggested, after I published mariadb ports to host, it worked perfectly . I’m on windows 10 pro and using docker desktop. Effectively, everything points to localhost. There was no need to find docker-machine ip.

Thanks a lot @revant_one

This pointer too nailed the problem precisely. I’m not sure why there is mismatch of branch versions in instructions at : https://github.com/frappe/frappe_docker/blob/develop/development/README.md

I’ve put pull request suggesting the change in user guide. Request you to check.

PR is merged.
Thanks for the fix!
