Duplicate Recurring Invoices

[Dave Swift]

Yes, they're running.

@Dave-Swift looks like the docs are quite obsolete. I am cleaning them up now.

[girish]

@Dave-Swift I think I have found the issue. Looks like we active the internal cron and the package also has a cron of it's own. Getting fixed.

[girish]

@Dave-Swift Can you please try with package 1.12.0 ?

[Dave Swift]

@girish Thank you. I will let you know after the next recurring invoice goes out in the beginning of March.

[Dave Swift]

Unfortunately the double billing is still occurring.

[girish]

@Dave-Swift can you check if /app/data/env has INTERNAL_QUEUE_ENABLED=false ?

[Dave Swift]

Yes it does.

[Dave Swift]

Any ideas on how to solve this? I love InvoiceNinja but haven't fully implemented it because of this issue. Should I just try a fresh install?

[Dave Swift]

To investigate further, I performed an analysis of all the running processes on my system using the ps aux command.
Here are the relevant processes I found:

1. Queue Worker Process:

www-data 2129 0.0 0.3 194696 104424 pts/0 S 23:12 0:01 php /app/code/artisan queue:work database

This process is running the Laravel Artisan queue:work command with the database queue connection.

2. Schedule Worker Process:

www-data 37 0.0 0.3 192452 103156 pts/0 S 22:18 0:05 php /app/code/artisan schedule:work

This process is running the Laravel Artisan schedule:work command, responsible for executing scheduled tasks.

Apart from these processes, I found multiple Apache web server processes and a Supervisord process, which I don't think are related to the queue or InvoiceNinja application.

Is the presence of a single queue worker process and a separate schedule worker process expected in the standard InvoiceNinja setup on Cloudron?

Could the schedule worker process be contributing to the duplicate recurring invoices issue, or is it unrelated?

Are there any other processes or configurations I should investigate further to identify the root cause of the duplicate recurring invoices problem?

Thank you for your assistance and guidance in resolving this issue.

I was reading again through the cron section at https://invoiceninja.github.io/en/self-host-installation/ and I while I don't fully get it, I think the root issue is, that we run both a scheduler and the queue worker and it seems one is sufficient. But I am not 100% sure from those docs.

I have published a new package which disables the scheduler and only relies on the queue. @Dave-Swift can you check if this solves the problem?

[Dave Swift]

Thanks @nebulon. I have installed the update and will let you know when I have enough data. Fingers crossed.

[Dave Swift]

@nebulon My recurring invoices are now not running at all.

[nebulon]

Alright, I've brought back that service then. I guess we have to debug this in more detail then.

[Dave Swift]

Thank you, I updated and payment went through right away.

I wonder if recurring invoices I made before the first change you made were still billed twice but the new ones will only be billed once?

Do you think that is possible? I tried doing some daily test recurring invoices and they were not billed in duplicate.
